I have a form on my website.
Inside this form a some emoji buttons.
If a user clicks one of this buttons they add an emoji to a <textfield>,
but they look like this " :) ".
So how can i replace the :) Emoji with images.
Example: If a user click a button it should add <img src="img/emoji/1.png"> and display it.
Use the UTF8 characters for the emoji's. Since the UTF8 emoji's are considered text characters, you don't need to use any HTML for this, and they will render in normal textarea's and text input's without anything special.
Here's a reference for some unicode UTF8 emoji's. In your buttons code, replace the ;) or whatever with the code for the UTF8 symbol-- for example on the table in the link it shows the code U+1F600 for a smiley face. In your script you want to say it as \u1F600 in quotes. This will render the emoji character. Most browsers, especially on mobile, have good support for these characters, but you can bolster that by importing an emoji font using css.

Addendum: You can even cut and paste UTF8 emoji's directly into your code. Since they are valid characters in UTF8, they are valid code.. you could even use them in variable names 😎

The <sup></sup> tag is used for superscripts. Creating a code block is done with backticks. The issue I have is when I try to create a superscript within a code block, it prints out the <sup></sup> tag instead of formatting the text between the tag.
How do I have superscript text formatted correctly when it's between backticks?
Post solution edit
Desired output:
A2 instead of A<sup>2</sup>
This is not possible unless you use raw HTML.
The rules specifically state:
With a code span, ampersands and angle brackets are encoded as HTML entities automatically, which makes it easy to include example HTML tags.
In other words, it is not possible to use HTML to format text in a code span. In fact, a code span is plain, unformatted text. Having any of that text appear as a superscript would mean it is not plain, unformatted text. Thus, this is not possible by design.
However, the rules also state:
Markdown is not a replacement for HTML, or even close to it. Its
syntax is very small, corresponding only to a very small subset of
HTML tags. The idea is not to create a syntax that makes it easier
to insert HTML tags. In my opinion, HTML tags are already easy to
insert. The idea for Markdown is to make it easy to read, write, and
edit prose. HTML is a publishing format; Markdown is a writing
format. Thus, Markdown's formatting syntax only addresses issues that
can be conveyed in plain text.
For any markup that is not covered by Markdown's syntax, you simply
use HTML itself. ...
So, if you really need some text in a code span to be in superscript, then use raw HTML for the entire span (be sure to escape things manually as required):
<code>A code span with <sup>superscript</sup> text and escaped characters: "<&>".</code>
Which renders as:
A code span with superscript text and escaped characters: "<&>".
This is expected behaviour:
Markdown wraps a code block in both <pre> and <code> tags.
You can use Unicode superscript and subscript characters within code blocks:
class SomeClass¹ {
}
Inputting these characters will depend on your operating system and configuration. I like to use compose key sequences on my Linux machines. As a last resort you should be able to copy and paste them from something like the Wikipedia page mentioned above.
¹Some interesting footnote, e.g. referencing MDN on <pre> and <code> tags.
If you're luck, the characters you want to superscript (or subscript) may have dedicated codepoints in Unicode. These will work inside codeblocks, as demonstrated in your question, where you include A² in backticks. Eg:
Water (chemical formula H₂O) is transparent, tasteless and odourless.
I've listed out the super and subscript Unicode characters in this Gist. You should be able to copy and paste any you need from there.
A simple html page has FORMATTED text - not fancy - line breaks, and italic.
I want to have a button that takes this formatted text, and copies it to the clipboard, formatted (it is planned to be pasted into some LibreOffice document later).
Couldn't find how to do it.
I tried ZeroClipboard, and a suggestion to parse the text, replacing ""-s to "\r\n". That indeed does the trick for line breaks, but what about italic?... Any means to get this functionality?...
When you create an italic tag the responsible for formatting the document and showing the text properly is the browser. If you want to copy the text you should get the text already parse and render by the browser or parse yourself the text like you did with break lines. For italics when you find a ... tag you must create the adequate text. That is, text in italics, but that depends on the language you are using, but i'm sure it can be done.
OK,
Turns out that ZeroClipboard had this functionality (of rendering the HTML text upon paste), but have disabled it.
However, the version that supports it can be found at: https://github.com/botcheddevil/ZeroClipboard
Note:
You may find that in this version, creating the client, binding the flash to a component, and handling the events are rather different than the documentation of current version of ZeroClipboard (https://github.com/zeroclipboard/zeroclipboard/blob/master/docs/instructions.md
I am using html2pdf library for genarating pdf with bookmarked index. By default it seems to work well for English content but i need to generate content that includes English & Arabic text. The "aefurat" font seems to work relatively good, except some special characters (’, ‘, “, ”, ...) that are rendered as boxes ([]).
The code I used is,
require_once(dirname(__FILE__).'/../html2pdf.class.php');
$html2pdf = new HTML2PDF('P', 'A4', 'en', true, 'UTF-8', 0);
$html2pdf->setDefaultFont('aefurat');
$html2pdf->writeHTML($content);
$html2pdf->Output('bookmark.pdf');
A Sample content that includes arabic and special chararacters is,
’This is Arabic’ "العربية" Example With TCPDF... some text here some
text here some “text here”.
Wondering if I need to use some other font or alter some configurations. Kindly advice me.
I tried by make Excel file & import as a csv file in sqlite. But it shows me in normal font rather than bold or italic font.
In my app, I uses the sqlite database and fetches data from it. I want to display some text in italic font,How can i do that??
Does Sqlite supports Italic?
yOu should store data with rules, as in case html we store it as <b>topic/b><i>this is topic</i> i mean by adding proper tagging before save.
I am not share about ios or xcode how but you should add some extra information to text before saving the text.
When you read bold text, you are interpreting a "strong" meaning. This strong meaning can be emphasized in a number of different ways (for instance, all caps: BOLD). Your text shouldn't contain information about how the information is presented (style), but it SHOULD contain information about the meaning (structure). Keeping these two separate gives you more flexibility to change how the text is presented if, say, you wanted to change your website template or application design. You could choose to display strong text as bold, all caps, all caps and underlined, etc. on a whim.
I recommend some subset of HTML, as it is structural by nature and very widely used. In HTML, the bold tag exists (<b>; however, it is stylistic, so the <strong> tag is recommended to encode the strong meaning instead).
Databases don't support encoding; however, you can encode the text yourself before sticking it in the database. Here is an example of an HTML-encoded string:
<p><strong>An HTML-encoded string</strong> inside a paragraph.</p>
When you extract it, you could choose to represent the strong text as bold:
An HTML-encoded string inside a paragraph.
Or as CAPS:
AN HTML-ENCODED STRING inside a paragraph.
Or even italic caps:
AN HTML-ENCODED STRING inside a paragraph.
There are many other ways to encode structure, including Mark Down (I believe that's what StackOverflow uses).
where you want to display it? in some label , textfiled or some other? change font type there where you want to display it
For example if you want to display it in UILable
then change the font type of UILabel
[<lblname> setFont:[UIFont boldSystemFontOfSize:<whatever_you_want>]];
It's your bad logic to fetch bold text from database.

I have several huge CSVs with lots of accented characters in html hex code: é for é and lots of others, even – for –, etc.
My site is a wiki for people to update listings. So when they are presented a textarea for update, the existing content is filled in, and obviously those hex codes will be shown.
Should I be bothered replacing those codes with actual accented characters, or just leave it as it is? I wrote a script to replace the characters, but somehow the output are weird characters. Probably the format saved in Ruby isn't in UTF-8 format.
By default my site is in UTF-8, and the accented characters are displayed properly with some html coding in the view.
Please advise. Thanks.
Could you clarify what the problem is?
If your data (CSV) is in UTF-8, and the default encoding of your site is UTF-8, then all you would need to do is make sure that when users are editing content, that content is properly treated as UTF-8.
You may not need to display the markup to the users. Perhaps you could leverage a WYSIWIG editor package like TinyMCE?
