I want to display "x2" (second power of "x") in a UILabel. How can I do it?
Thanks in advance!
There’s a Unicode character 0x00b2 (², superscript two) that should do the trick.
Actually, I've found the answer myself and it's really simple. In IB there's the "Special characters" menu, which contains lots of characters including second power of "x". Then you just click on the label, press cmd+1 and drag'n'drop the character into the "Text" field of the Inspector window.

I cannot figure out how to do this for the life of me apart from doing a find-replace on 4 spaces and converting to tabs (Version 0.10.2). I can't think of an editor/IDE that doesn't have a specific feature to do this. Does VSCode?
Since fix of: https://github.com/Microsoft/vscode/issues/1228 the editor supports it out of the box. Simply go for:
F1,
indentationToSpaces or indentationToTabs (depending on your need)
Enter.
Another way to do it is click the current indentation (Tab/Spaces:n) on the footer which will open your indentation options where you can select what you want to do.
If you are trying to convert non-leading tabs to spaces (or vice versa) you can use a regex search and replace.
Press CTRL + H
Click the .* button to search using regular expressions.
To search for tabs enter [\t] in Find box.
Enter spaces in Replace box and perform your replace.
Search box in regex mode:
To round out these answers, I will add my take for converting each tab to n spaces.
Highlight a tab character
Use CTRL + F2 select all occurrences
Press SPACE n times
This is the easiest way to do this (going beyond only converting leading tabs).
Note that this does not convert consecutive tabs to k spaces. It converts each tab. For consecutive tabs please see my comment on jrupe's answer. You will need VS Code find and replace with regular expressions to accomplish that.
Select Replace: CTRL-H
Enter Horizontal Tab in Find box: hold ATL and type 009 on the keypad.
Enter a space(or more spaces) into the Replace box: press space bar
Press Enter to begin replacing Tabs with Space(s).
Press F1 and then type into textbox convert indentation to spaces or whatever you want ones
On Visual Studio, Ctrl+K+F did the trick for me.
Fast forward to 2020/2021, there are some extensions that will give us that conversion. I have just needed that functionality (hence I found this article), and searching for extensions I found:
geocode.spacecadet - providing both TAB->SPC and SPC->TAB, but not updated since 2017, with 1.3k installs, 3.5 review
takumii.tabspace - TAB->SPC, from 2020, 1.5k installs, no reviews
pygc.spacetab - SPC->TAB, from... wait, literally yesterday! (or today depending on your TZ), 2 installs, no reviews
I would like to display a unicode character (the speaker symbol U+1F50A) in label.
Is it possible to enter this symbol in Interface Builder?
Yes, you can click "Edit" > "Special Characters…" — there you can find all unicode characters (including the emoji) and copy/paste them where you set the label text in Interface Builder.
EDIT:
In Xcode 6 it's "Edit" > "Emoji & Characters"
Xcode 7+: "Edit" > "Emoji & Symbols"
For those who tried doing it programmatically, but failed, just use this:
label.text = #"\U0001F50A";
Do it programmatically.
Declare an IBOutlet for the Label, with the means of NSString type:
// UTF-8 Hexadecimal Encoding
NSString *myString = [NSString stringWithUTF8String:"0xF09F948A"];
myLabel.text = myString;
Also, take a look at this question.
In Xcode 8/Swift 3 the easiest is to use the unicode escape:
let a = "\u{1F50A}"
It's fun why few people knew this.
You can enter Unicode-symbols directly by holding "Option" and entering hex digit.
All you need: (Sierra example)
goto "Preference -> Keyboards -> Input Sources" and search for "Unicode Hex". It should appears under "Others" section. Next add it and then you be able enter Unicode-char anywhere just selecting this input source.
For example: ✓ = (Alt+2713), € - (20ac), etc.
Most interesting section from 2100 to 2800.
Full list you can found here - Unicode table
P.S.: This method sutable only for four-digit Unicodes
I can write Arabic/Urdu/Persian on MS Word or Notepad just fine, but whenever I insert any English word or number, the sequence is just disturbed and seems like the all the words have been shuffled in the sentence.
Look at the example below:
یہ ایک مثال ہے اردو کی ...
Now I inserted an English word and it became:
یہ ایک مثال ہےword اردو کی ...
So you can see almost all of the words have been jumbled ... what is the solution for that ?
For example:
باللغة العربية “keyboard” انا أريد أن أعرف الكلمة
Finish typing the Arabic word and add a space after it (this space separates the embedded text from the Arabic text to its right).
Insert special character U+200F (to render the preceding space an Arabic character). The character name is "Right to Left Mark".
Insert special character U+202A (to begin the left-to-right embedding). The character name is "Left to Right Embedding".
Insert another space (to separate the embedded text from the Arabic text that will continue to its left).
Change the keyboard to e.g. English and type the left-to-right word.
Insert special character U+202C (to restore the bidrectional state to what it was before the left-to-right embedding). The Character name is "Pop directional formatting".
Change the keyboard back and continue writing in Arabic.
If you're working in Microsoft Office or Open Office, the "special characters" can be found under "insert" [Insert -> symbols -> other symbols -> special characters in MS 2013]. Scroll through until you find the character with the appropriate Unicode number, and if the Unicode number does not appear in your version of MS Word, select it by its name [as indicated above].
You can also add the character by writing it's unicode and then selecting it and pressing Alt+X - but that can be confusing because it needs constant change between Arabic and English.
All of the special characters involved in this little manoeuvre are invisible characters (their job is simply to change the direction of the text) so don't be surprised if it looks like you're not inserting anything.
Pay attention to select the RTL option from the ribbon when the majority of your paragraph is RTL and keep it selected [as shown in the picture in this answer https://stackoverflow.com/a/46050171/8558867 ].
Before you start typing in Arabic/Persian make sure you have chosen "Right-to-Left-Direction" button. This button can be found on Paragraph tab just left side of AZ sorting button. Also select "Align Text Right" button which can be found in Paragraph tab left side of Justify button.
Start typing your language
Before putting an English word put an space then select left ALT + SHIFT and type your English word
Once finished your English words select right ALT + SHIFT and then put a space and keep typing your language again
Hope this helps
This is OK; they're not shuffled: you're seeing them in LTR rendering mode.
You just need to make them right-to-left. In Notepad or Word, press right Ctrl+Shift to make their direction right-to-left and it will be okay. (It's like having <p dir="rtl">...</p> in HTML).
The control characters LRE and RLE (0x202A and 0x202B) and also LRM and RLM (0x200E and 0x200F) need to be applied to the whole paragraph, i.e they should come at the beginning of the sequence. Some text display widgets of some platforms may discard these control characters though, particularly older (pre-2000) platforms or those who do not support Unicode bidirectional algorithm correctly. Newer OS'es and programs should be fine; try with Windows Notepad for example.
I personally recommend using the platform's means to make the text RTL, and avoid special control characters because they're invisible and may cause surprising results if they go out of control. So you'd better use Word's API to make the text RTL, or if your output is HTML put them in <div dir="rtl">...</div> tags. For plain text file, user has to manually press the Ctrl+Shift keys himself.
Edit: this was written as a clarification answer to the first answer here, I later edited the first answer and added the important notes I wrote here [the edit still needs approval though].
I was able to fix my text by following the steps in the first answer here.
In case anyone faces troubles while following the steps, let me clarify some things:
If you are entering an English word in an Arabic text, make sure that RTL option in the ribbon is selected [circled in red in the following figure]:
Keep it selected throughout the paragraph irrespective of the language you are using [as long as the majority of the paragraph is written in an RTL language like Arabic or Hebrew].
Where to find the special characters and how to insert them:
You can write the unicode of the character and then select it and press "Alt + X". However, this can be a bit confusing because of the need to change back and forth between English and Arabic to write the codes, so the best thing to do is enter them 'manually' by inserting their names.
You can do that by going to Insert -> Symbol -> More Symbols -> Special characters [scroll down]. Then select the name of the characters you need to use instead of its unicode.
The names of the characters you'll need to use [as specified in the first answer here] are:
"Right to Left Mark" : U+200F.
"Left to Right Embedding": U+202A.
"Pop Directional Formatting": U+202C.
As the first answer says, nothing will appear on the screen because it's a non-printing character, so it's normal if you felt like nothing happened when you insert.
If you need to do it the other way around, that is, insert a Hebrew or Arabic word in an English text, just reverse the use of unicodes -- Or follow the steps in the following link: https://superuser.com/a/1247476/767967
If you want to know more about what the special characters do and what it means to make your paragraph LTR or RTL, visit the following link: http://dotancohen.com/howto/rtl_right_to_left.html#Directionality
Select the paragraph (e.g. using triple click) and use the button for right-to-left direction (¶◀) in the Paragraph section of the Start pane.
As Hossein’s answer explains, the issue is the directionality in the paragraph. It changes to left to right when you insert a Latin letter, and you need to fix this manually.
You need to add an invisible RLE Unicode Character at the start of the line [^].
It's : 0x202B hex = 8235 decimal or RIGHT-TO-LEFT EMBEDDING (RLE).
It's necessary for Notepad but MS-Word is able to handle it. you need to right align your text correctly.
How to enter RLE: http://www.fileformat.info/tip/microsoft/enter_unicode.htm
In word processing, you have a main text direction which is either left-to-right or right-to-left (or top to bottom, but let's ignore that :-), and you have a text direction for individual characters, which will also be left to right or right to left.
The word processor splits the text into chunks of strings with the same character ordering, then displays these chunks according to the main text ordering.
It seems that your main text ordering was left to right. As long as all your text is arabic, there is just one chunk with arabic text. You see already it is displayed left aligned and not right aligned because the text ordering is left to right. The characters are displayed right to left because that is how arabic is displayed.
When you inserted latin text, you had three chunks: Arabic, latin, arabic. These three chunks are displayed left to right because that is the main text ordering. That would be fine for text that is mostly latin (like "The arabic words for dog and cow are ... and ..."). For text that is mostly arabic with the occasional latin word, you need to change the main text ordering to "right to left".
Just follow this:
Copy and paste the arabic text into from word or text document to ADOBE Illustrator.
Save the illustrator document as in .EPS format.
Open indesign and place the .EPS document into the place you want.
Since indesign can't handle arabic text issue by it self, this method will help many designers.
I can change the style of a cell using conditional formatting. But there I would be limited to a maximum of 3 cases it can handle.
What I want to do is to get the value of a cell, convert it in a certain way and set the result as the cells background-color.
The simplest example would be cells with values between 0 and 10, resulting in gray-steps between white and black.
Is this possible? Are there ways to set the background-color of a cell automatically?
Thx!
This has been implemented in libreoffice 3.6 (see the release notes)
Format one cell how you want (not one you want to conditionally format).
Press F11 to get the Styles dialogue box
Use the button one from the top right, which is "New Style From Selection"
Type the name you want, e.g. BlackBack
Then do the conditional formatting of the relevant cells, choosing BlackBack
Source: http://www.oooforum.org/forum/viewtopic.phtml?t=61294
Note that you can find "Conditional Formatting" under the Format menu in OOo Calc.
As Joey said: "As far as I can see conditional formatting in OOo cannot do that. Excel has no problems there, though."
It's simply not possible... :-/
I saw a very strange issue with UITextField control. When typing in UITextField after typing a few characters when typing space characters it puts "." characters at the end of the string.
Can anyone know possible solution for this??
Thanks,
Jim.
Do you mean when you enter 2 spaces? If so this a feature that means you don't need to switch to the numeric keyboard to enter the full stop
