I have a CListCtrl object and I use:
AddData(m_listControl, 0, 0, " Abc ");
This works fine in older version of Visual Studio (2008).
However in Visual Studio 2013 I am using UNICODE character set, and the above displays a strange font in the List Control Box.
Can someone please tell me how to insert (AddData or another way) so that the CListCtrl displays english character set?
Use TEXT( " Abc " ). TEXT() macro makes strings Unicode or ASCII depending on compiler settings.
Well, why did you use this title:
"Unexpected font in CListCtrl?"
your problem has nothing to do with a font.
It also has nothing to do with list view control. It is AddData function that is giving you a hard time.
I am sure that in parameter list, the fourth argument is defined as const char*. You will have to change function’s signature.
Try LPCTSTR as type.
Than, follow i486's answer.

just installed VS22 and I can't seam to figure out how to turn on hilighting matching braces. It was working in VS19 and seamed like it was default but it's not working here.
What setting do I change?
I've tried changing Tools>Options>Environment (Show settings for "Text Editor") >Fonts and Color>Brace Matching(Hilight and Rectangle)
Because I read that the default colors are very nuance and hard to notice, but still nothing.
Should I just try reinstalling?
As you can see, it hilights key words and other places in the code where those words match up, but not the brackets. Same result no matter which side of the bracket I click on
I am working on an MBCS app using MFC. I am trying to support Asian languages. For the purposes of this discussion, we'll say I'm trying to support Chinese. I am able to support Pop up dialogs via MessageBoxW and Dialog SCREENs by pasting Chinese characters directly into the RC file. I can't get file menus to work using either resource view or editing the RC file directly. Whenever I type in ANY Asian character, the screen shows ???. One ? for each character. I have tried modifying the menu in C++ using ModifyMenuW. I get more question marks. Visual Studio shows everything working, and the RC file is unicode (UTF-16). I can't easily convert my project to unicode mode. Spanish, French, and German all works fine (one of the Essets in German doesn't work, but that isn't a show stopper). What should I try next?
Thanks in advance!
Well, the easy answer would be change the application to Unicode, but this is not always simple, or possible at all.
Concerning using Unicode in a MBCS application, some things are possible and some others not. For example, I have made a MBCS application displaying and editing translations of program strings (messages, menues etc) in a ListView control, however ListView does have a specific message to turn it to Unicode (LVM_SETUNICODEFORMAT) and support operations (see also CCM_SETUNICODEFORMAT). Menus aren't controls though, but they do have "wide" (Unicode) functions.
If you want to use Unicode in your application, there are some tests you need to make. Success is not guaranteeded, but you can at least draw some conclusions and determine whether what you want to do is possible.
Test1:
You mentioned trying ModifyMenuW(), but this will try to modify an existing menu. Instead, try InsertMenuW() or InsertMenuItemW(). Any unicode string should be displayed properly, so try not just Chinese, but other laguages too (eg Greek or Russian). And btw, I can't see how French works and German doesn't (they use the same codepage - West European). What's the system codepage of your test-machine?
Test2: (if the above has failed)
Try changing the whole menu (SetMenu()) with having a single (unicode) menu item as its root.
Test3: (if the above have failed)
Then you need to check whether the window containing the menu must be Unicode. Create a simple "Hello World" Win32 application, or find a sample, if Visual Studio does not do this for you (these basically register the window class, create the main window and start the message-loop) - you must add a menu too, using the "wide" version of the menu functions explicitly. If this doesn't work, try changing the code that creates the window to unicode. This way you will know whether you need a unicode window, to own the menu.
Please make these tests and let us know the results. I will further post if needed.
I can see special characters ąęį when I do form design on static text label:
These character are changed while running:
If I set these characters in programming way I have:
How can I ensure that the correct characters are displayed instead of question marks as shown in the screenshot above?
UPD:
My project is Multi-Byte. I found that in another computer I can see special characters. Why?
You need to use Unicode character set for this to work correctly, and my guess is that you're using MBCS character set now.
You could change it in the project properties. Refer to this screenshot:
Visual studio editor is fully Unicode, meaning it could display such special characters as you type when you're designing the dialog. However, if your application is not built with Unicode support, it won't be able to display thsoe characters when it runs. Thich is why you see the ??? replacing the Unicode text when you run the application.
If you get different results on different computers this is obviously due to differences in system settings.
The setting that controls this is called "Language for non-Unicode programs", and can be found under Control Panel, Language, Change date, time or number formats. Unfortunately it's a global setting (ie cannot be set per application or programmatically) and requires a re-boot.
Consider making your application Unicode, if possible (and meaningful cost- or effort-wise).
Visual Studio allows the Unicode character Zero Width Space (U+200B) to be pasted into the code editor. This character is (as the name implies) invisible.
This can lead to nasty bugs such as the one I just spent time troubleshooting where HttpWebRequest.CreateHttp(string url) threw a UriFormatException when passed the innocuous-looking string literal "http://www.umich.edu".
The exception occurred because the first character in that string literal is not h, as it appears, but is the Zero Width Space character. It was put onto the clipboard when I copied the URL from the body of a web page, and was dutifully pasted into my code by Visual Studio when I hit Ctrl+V in the code editor window.
Turning on the "View White Space" option (Edit > Advanced > View White Space) does not cause Visual Studio to reveal that there's a Zero Width Space character present.
I would like Visual Studio to:
Give some kind of indication or warning when there's a Zero Width Space character (or other invisible character) in a string literal in my code, and/or
Prevent such control characters from being pasted into the code editor in the first place.
Is there a way to make Visual Studio do this?
The Gremlins tracker for Visual Studio Code worked for me.
https://github.com/nhoizey/vscode-gremlins
P.s.: IntelliJ recognizes those hidden troublesome chars OOTB
As of December 2021, Visual Studio Code introduced highlighting of invisible characters.
From this
to this
Preferences -> Settings (ctrl + ,) -> search for "invisible characters" -> tick "Editor › Unicode Highlight: Invisible Characters"
This option should be on by default.
If you are using "VSCODE" then it's simple, just install gremlins in vscode. After Installing where there are gremlins remove those spaces(with red line) and you are good to go. It works for me.
It is possible, but I don't know how is it done.
Use the Windows Charmap.exe applet. In the Font combobox select a font that has a lot of glyphs, Arial Unicode MS is a very good choice. Tick the Advanced view checkbox and type "super" in the Search box. The grid will show all superscript glyphs, select and copy from that and paste into your source code.
Or copy/paste one of these: ¹²³⁴⁵⁶⁷⁸⁹⁰
Subscript characters: ₀₁₂₃₄₅₆₇₈₉
Adding more details to complement #HansPassant's answer. Other frequently used sets which can be used as is by copy/paste:
Superscript small case letters: ᵃᵇᶜᵈᵉᶠᵍʰⁱʲᵏˡᵐⁿᵒᵖʳˢᵗᵘᵛʷˣʸᶻ
Subscript small case letters: ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ
If you're wondering why few letters are missing in above series then please read below posts:
Where are the other letters in this Unicode block?
Why does the unicode Superscripts and Subscripts block not contain simple sequences of all letters?
Why is there no character for "superscript q" in Unicode?
Since there is a tag visual-studio-2012, I assume you are running Windows. There is a great opensource program called WinCompose, which allows to use easy-to-remember and intuitive shortcuts for a huge amount of Unicode symbols, including numerical super- and subscripts. Every shortcut is invoked via a Meta key (e.g. Right Alt), for example:
Meta + ^ + 1 gives ¹;
Meta + _ + 9 gives ₉.
WinCompose also supports search, can be run in background, and eliminates tedious procedure of calling Character Map with subsequent copy-pasting or remembering the Unicode charsets (but the latter are also listed):
P. S. I'm not affiliated with this software by any means. Just a happy user.
One more way for WPF users,
<TextBlock >
<Run>x</Run>
<Run FontSize="8" BaselineAlignment="TextTop" >2</Run>
</TextBlock>
Change BaselineAlignment to TextBottom if you want to use as subscript.
In VsCode download the extension "Fast Unicode Math Characters".
The hotkeys for ₂ is \_2.
The hotkeys for ² is \^2.
Looks like there are some simple tags that you can use to make any text superscript/subscript. The superscript tag is <sup> and the subscript tag is <sub>.
https://www.w3schools.com/tags/tag_sup.asp
use (Ctrl + Shift + P) command to apply superscript and subscript in Visual Studio.
This is how usually I tend to do it on Mac.
In the VS code, hit (Control + Command + Space) to bring up the Character selector and search for 'superscript' in the search box.
Click on required superscript and add it. And here is the result. Screenshot are from the VS code only.
This approach should work across most of the apps in the Mac. Tested in MacOS 12.5. (Monterey)
There are several solutions. Personally, I simply formaat the label text in Word, use a screen capture and save it as an image that I use with a label.
