Java 7 Bug: Displaying Telugu through Unicode literals - unicode

While displaying Telugu through unicode in Java 7,java is rendering the blends incorrectly.
For example, here is a simple snippet to display a word in HTML. It works great. All the browsers display the text correctly.
<!DOCTYPE html>
<html>
<body> &#x0C05&#x0C2E&#x0C4D&#x0C2E </body>
</html>
However, the same literals when used in Java (here i am setting the same text to a text area, the display gets messed up.
Font text_font = new Font ("Gautami", Font.PLAIN, 30);
jtaInput.setFont(text_font);
jtaInput.setText("\u0C05\u0C2E\u0C4D\u0C2E");
Has any one facing issues with Java 7 in the context of unicode character rendering? Any tips/ideas to get over this?
thanks

Try using different fonts; The font that worked in Java 5 and Java 6 stopped working in Java 7. When I moved to a new Font, the display came back correctly.

Unity - Displaying Burmese (Zwagyi) text

We're currently developing a game in Unity (2019.4.28f1). This game is played internationally. We'd like to add support for languages other than common Latin written languages. Currently, we're trying to implement support for Burmese, but aren't making much progress.
Finding fonts to display Burmese isn't a big issue. As you can see in the image below, we manage to display all characters that are supposed to be displayed.
However, the big problem here is that the displayed order of symbols isn't the same as what it's supposed to be (see image below for the desired result).
We've tried several fonts that use either Unicode or Zwagyi encoding, but none of them seem to display characters in the correct order. Currently, we're using a padauk font from here, which is supposedly Unicode encoded. Then, within Unity, we applied to following settings to that font:
So, if one of you knows more about this and can share some information with me, that would be much appreciated!
Thanks.
We've already found a solution for this! Before setting the text of the text component convert the Unicode codes to Zwagyi and it'll display the text in the correct order!
All the credits go to this guy who put in the effort to make a tool for these use cases!
Of course, you still need a (Unicode) font that supports these (Burmese) symbols.
Example:
Text textComponent = GetComponent<Text>();
textComponent.text = mmfont.Net.Converter.Uni2ZG(yourUnicodeText);

Icon Font causes Compatibility Mode in IE8

I'm having a problem where icon fonts are causing IE8 to go into Compatibility Mode. And correspondingly, if IE8 is forced into Edge mode (eg. via <meta http-equiv="X-UA-Compatible" content="IE=edge" />) then IE will crash.
Specifically, I have a custom icon font that I'm using, and it's currently mapped to the unicode Private Use Area of the Basic Multilingual Plane. The font starts at \f000 and goes up to around \f360.
I found a couple articles that suggest that assigning to the unicode Private Use Area is the problem:
http://adactio.com/journal/6555/
http://www.clockwork.net/blog/2013/10/08/657/how_to_avoid_forced_compatibility_mode_in_ie8_and_keep_your_custom_fonts
Things that I've tried to fix it:
Re-mapping the range to \e000 - \e360
(Glyphicons uses the \exxx range)
Re-mapping the range to \0000 - \0360
(includes the Latin range, Linguistic scripts, and Other European Scripts)
Neither of these solutions works though, IE8 continues to crash and/or go into compatibility mode. I haven't yet tried limiting the font to strictly the Basic Latin range because I have too many glyphs to fit in the 127 available spots.
I've also been able to get both FontAwesome and Glyphicons to crash IE8, also it seems to happen less frequently than with my font. Most of the time the initial page load will work, and then hitting refresh will cause the problem.
Anyone have any other ideas on what I can do?
PS: I'm not concerned about other IE8 CSS #font-face issues, like those discussed here IE8 CSS #font-face fonts only working for :before content on over and sometimes on refresh/hard refresh. I've already applied the techniques there to solve those issues.
Long story short, there are two ways to solve this:
assign to the Basic Latin Range : U+0020 to U+007F
assign to the Low Surrogates Range : U+DC00 to U+DFFF
I found this through unit testing various ranges with my custom icon font using a grunt-webfont build process.
I didn't exhaustively test every range, but I found these two to work, and to be sufficient.
Notes: The Basic Latin Range starts from U+0020 not U+0000.
The Low Surrogates Range has a larger address space, and so is preferrable if you have a lot of glyphs. It also has the advantage of rendering square boxes if the glyph fails to load, as opposed to assorted Latin characters as the Basic Latin Range does.

Rendering Japanese text in Flex

Flex documentation says that we need to include fonts for Japanese characters, Flash Player can't access fonts from the system in which it is running. If my flex application has to support all languages, should I embed an entire font library into swf-file? In my case data is fed from MySQL, so I can't fall back to runtime loading.
Is there any ttf font equivalent to Arial Unicode MS font?
Kindly help me out.
If you are using Flex 4 SDK then it should happen automatically - you just need to define a font fallback chain such as,
fontFamily: "Hiragino Kaku Gothic Pro W3","MS GOTHIC","_sans";

Blogger and unicode?

I have two questions
Can this code be added to blogger?
Can this code embed unicode fonts? and if can, please tell me the link how to do it.
I can't see your code Kotaro ,
but any code can added to blogger and and by default embedding font in web is not available . but you can use CSS 3.0 to force user to use from the font you like, this css property is
font-url
and you can use it as any other css property like
<div style="direction:ltr;text-align:left;font-size:small;font-url:('../resources/fonts/YourFont.ttf');"> you code </div>
just note that this CSS property just available at css 3.0 and now just Firefox 3.5 supports it so I recommand you Ignore it for now,
if you want to show a speciall text just use from a font that you know your users have it, like (Arial , Tahoma , Verdana ) for windows usres
for code you can use these software

that is a opensource software

How to disable phone number linking in Mobile Safari?

Safari on iPhone automatically creates links for strings of digits that appear to the telephone numbers. I am writing a web page containing an IP address, and Safari is turning that into a phone number link. Is it possible to disable this behavior for a whole page or an element on a page?
This seems to be the right thing to do, according to the Safari HTML Reference:
<meta name="format-detection" content="telephone=no">
If you disable this but still want telephone links, you can still use the "tel" URI scheme.
Here is the relevant page at Apple's Developer Library.
I use a zero-width joiner ‍
Just put that somewhere in the phone number and it works for me. Tested in BrowserStack (and Litmus for emails).
To disable the phone parsing appearance for specific elements, this CSS seems to do the trick:
.element { pointer-events: none; }
.element > a { text-decoration:none; color:inherit; }
The first rule disables the click, the second takes care of the styling.
Add this, I think it is what you're looking for:
<meta name = "format-detection" content = "telephone=no">
I was having the same problem. I found a property on the UIWebView that allows you to turn off the data detectors.
self.webView.dataDetectorTypes = UIDataDetectorTypeNone;
Solution for Webview!
For PhoneGap-iPhone / PhoneGap-iOS applications, you can disable telephone number detection by adding the following to your project’s application delegate:
// ...
- (void)webViewDidStartLoad:(UIWebView *)theWebView
{
// disable telephone detection, basically <meta name="format-detection" content="telephone=no" />
theWebView.dataDetectorTypes = UIDataDetectorTypeAll ^ UIDataDetectorTypePhoneNumber;
return [ super webViewDidStartLoad:theWebView ];
}
// ...
source: Disable Telephone Detection in PhoneGap-iOS.
To disable phone number detection on part of a page, wrap the affected text in an anchor tag with href="#". If you do this, mobile Safari and UIWebView should leave it alone.
1234567
You can also use the <a> label with javascript: void(0) as href value. Example as follow:+44 456 77 89 87
Think I've found a solution: put the number inside a <label> element. Haven't tried any other tags, but <div> left it active on the home screen, even with the telephone=no attribute.
It seems obvious from earlier comments that the meta tag did work, but for some reason has broken under the later versions of iOS, at least under some conditions. I am running 4.0.1.
My experience is the same as some others mentioned. The meta tag...
<meta name = "format-detection" content = "telephone=no">
...works when the website is running in Mobile Safari (i.e., with chrome) but stops working when run as a webapp (i.e., is saved to home screen and runs without chrome).
My less-than-ideal solution is to insert the values into input fields...
<input type="text" readonly="readonly" style="border:none;" value="3105551212">
It's less than ideal because, despite the border being set to none, iOS renders a multi-pixel gray bar above the field. But, it's better than seeing the number as a link.
I had an ABN (Australian Business Number) that iPad Safari insisted on turning into a phone number link. None of the suggestions helped. My solution was to put img tags between the numbers.
ABN 98<img class="PreventSafariFromTurningIntoLink" /> 009<img /> 675<img /> 709
The class exists only to document what the img tags are for.
Works on iPad 1 (4.3.1) and iPad 2 (4.3.3).
I have tested this myself and found that it works although it is certainly not an elegant solution. Inserting an empty span in the phone number will prevent the data detectors from turning it into a link.
(604) 555<span></span> -4321
I had the same problem, but on an iPad web app.
Unfortunately, neither...
<meta name = "format-detection" content = "telephone=no">
nor ...
0 = 0
9 = 9
... worked.
But, here's three ugly hacks:
replacing the number "0" with the letter "O"
replacing the number "1" with the letter "l"
insert a meaningless span: e.g., 555.5<span>5</span>5.5555
Depending on the font you use, the first two are barely noticeable. The latter obviously involves superfluous code, but is invisible to the user.
Kludgy hacks for sure, and probably not viable if you're generating your code dynamically from data, or if you can't pollute your data this way.
But, sufficient in a pinch.
A trick I use that works on more than just Mobile Safari is to use HTML escape codes and a little mark-up in the phone number. This makes it more difficult for the browser to "identify" a phone number, i.e.
Phone: 1-800<span>-</span>620<span>-</span>3803
Why would you want to remove the linking, it makes it very user friendly to have th eoption.
If you simply want to remove the auto editing, but keep the link working just add this into your CSS...
a[href^=tel] {
color: inherit;
text-decoration:inherit;
}
<meta name = "format-detection" content = "telephone=no"> does not work for emails: if the HTML you are preparing is for an email, the metatag will be ignored.
If what you are targeting are emails, here's yet another ugly-but-works solution for ya'll:
Example of some HTML you want to avoid being linked or auto formatted:
will cease operations <span class='ios-avoid-format'>on June 1,
2012</span><span></span>.
And the CSS that will make the magic happen:
#media only screen and (device-width: 768px) and (orientation:portrait){
span.ios-date{display:none;}
span.ios-date + span:after{content:"on June 1, 2012";}
}
The drawback: you may need a media query for each of the ipad/iphone portrait/landscape combos
You could try encoding them as HTML entities:
0 = 0
9 = 9
Same problem in Sencha Touch app solved with meta tag (<meta name="format-detection" content="telephone=no">) in index.html of app.
This answer trumps everything as of 6-13-2012:
<a href="#" style="color: #666666;
text-decoration: none;
pointer-events: none;">
Boca Raton, FL 33487
</a>
Change the color to whatever matches your text, text decoration removes the underline, pointer events stops it from being viewed like a link in a browser (pointer doesn't change to a hand)
This is perfect for HTML emails on ios and browser.
I too have this problem: Safari and other mobile browsers transform the VAT IDs into phone numbers. So I want a clean method to avoid it on a single element, not the whole page (or site).
I'm sharing a possible solution I found, it is suboptimal but still it is pretty viable: I put, inside the number I don't want to become a tel: link, the ⁠ HTML entity which is the Word-Joiner invisible character. I tried to stay more semantic (well, at least a sort of) by putting this char in some meaning spot, e.g. for the VAT ID I chose to put it between the different groups of digit according to its format so for an Italian VAT I wrote: 0613605⁠048⁠8 which renders in 0613605⁠048⁠8 and it is not transformed in a telephone number.
Another option is to replace the hyphens in your phone number by the character ‑ (U+2011 'Unicode Non-Breaking Hyphen')
I was really confused by this for a while but finally figured it out. We made updates to our site and had some numbers converting to a link and some weren't. Turns out that numbers won't be converted to a link if they're in a <fieldset>. Obviously not the right solution for most circumstances, but in some it will be the right one.
Break the number down into separate blocks of text
301 <div style="display:inline-block">441</div> 3909
Adding the meta tag to turn off format detection did not work for me. I was trying to display a zoom meeting ID in a <p> tag along with other text and iOS was turning that ID into a tel link. Additionally, I was targeting tel links via a[href^="tel:"] in order to give them custom styling so disabling the styles on tel links was not an option.
The solution I found was to wrap the ID number in a <code> tag. This seems to prevent iOS from messing with it.
