Title: Some fonts are missing from the font file list.
Post by: ander_cc on April 14, 2026, 08:58:13 AM
Like "Cascadia Mono", I can't see it in font name list. But can set in theme file.
Btw: When I was translating rc file, I noticed line 3409 had still read "version 13.00".
See attach files.

Hi ander_cc,

On my system the Cascadia fonts are there. See attachment.
Windows 11 Home 25H2, so seems they 'should' be there on Pro . . . it is not a Pelles IDE issue I think...

Try going to windows settings, personalization, fonts, then see what is there.

P.S. The title on the resource 9 file also shows 13 I believe

I also try it in my laptop, it is Win11 Home 25h2, and a Win10 pc, but miss some fonts too. Maybe this issue is only related to the Windows Chinese Edition.

You could be right, seems like it.  Did you check windows settings, personalization, fonts ..... that would be definitive if it is not showing there.

You might try Microsoft Store and see if the font is available to be installed.

Silly example to check if font exists
Code Select
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

int CALLBACK EnumFontFamProc(const LOGFONT *lpelf, const TEXTMETRIC *lpntm,
  DWORD FontType, LPARAM lParam)
{
    static int nCnt;
    OutputDebugString(lpelf->lfFaceName);
    if (!lstrcmp(lpelf->lfFaceName, (TCHAR*)lParam))
        nCnt++;
    return nCnt;
}

void __cdecl WinMainCRTStartup(void)
{
    HDC hDC = GetDC(GetDesktopWindow());
    //int nFont = EnumFontFamilies(hDC, TEXT("Consolas"), EnumFontFamProc, (LPARAM)TEXT("Consolas"));
    int nFont = EnumFontFamilies(hDC, TEXT("Cascadia Mono"), EnumFontFamProc, (LPARAM)TEXT("Cascadia Mono"));
    if (nFont) MessageBox(0, "font found", "Font", MB_OK);
    else MessageBox(0, "font not found", "Font", MB_OK);
    ExitProcess(0);
}

Hi Timo,

Compiling your code, I get the font not found message on Windows 7 Sp1.

Just an external font

I am deliberately filtering the fonts list. At least last time I checked, several years ago, not doing this filtering gave me many fonts I couldn't use.
I will have to think about this (when I can find the time)...

The version is in many places, this place is less important. I will fix this some day.

Quote from: Pelle on April 18, 2026, 05:58:35 PMI am deliberately filtering the fonts list. At least last time I checked, several years ago, not doing this filtering gave me many fonts I couldn't use.
I will have to think about this (when I can find the time)...
I check the output of your code paste below.
I think you filter the fonts with "GB2312_CHARSET" ? Maybe add "ANSI_CHARSET" could fix it.

Maybe. I need to check things more - this part of the IDE hasn't changed for 10+ years, so...

I'm confused - If it is an IDE issue then why using the same IDE do I see the fonts?
Attached screen shot -

First thing to do is check check windows settings, personalization, fonts to see if it is there.  It is possible and likely that putting it into the manifest it appears to work because windows will find the closest match to a font if that font is missing, as I recall. And verified with a web search

"Yes, Windows automatically substitutes a missing font with a default font (usually Microsoft Sans Serif or Arial) when it encounters a document or application requiring a font not installed on the system. This process ensures text remains visible, though it may change the document's formatting, layout, and appearance.
Key details on Windows font substitution:

    Automatic Process: When a specified font is unavailable, Windows attempts to map the missing font to an available one based on internal registry settings."

The filtering is supposed to exclude fonts not useful in the current locale. The problem is that for a (C) programming environment, it's hard to ignore the Latin alphabet.

So, ander_cc, changing filtering code in EnumFontFaceProc() from...
Code Select
if ((dwFontType & TRUETYPE_FONTTYPE) != 0 &&
        (pntm->ntmFontSig.fsCsb[0] & pls->lsCsbSupported[0]) == 0 &&
        (pntm->ntmFontSig.fsCsb[1] & pls->lsCsbSupported[1]) == 0)
        return 1;  /* unwanted font, but keep enumerating */

...to this, should fix the problem... right?
Code Select
    if ((dwFontType & TRUETYPE_FONTTYPE) != 0 &&

        (pntm->ntmFontSig.fsCsb[0] & FS_LATIN1) == 0 &&    /* <=== NEW */

        (pntm->ntmFontSig.fsCsb[0] & pls->lsCsbSupported[0]) == 0 &&
        (pntm->ntmFontSig.fsCsb[1] & pls->lsCsbSupported[1]) == 0)
        return 1;  /* unwanted font, but keep enumerating */
Not pretty, but I can't a better approach right now so this will have to do...

OK, cool. The fix will be in the next update.
