That's interesting. Is there already a CWS for this?
To implement the class WinGlyphFallbackSubstitution, It's necessary
to know if
a character is contained in a given font. So a ImplWinFontData
object is
generated as below code snippet when traversing every font face
utilizing
Windows API EnumFontFamilyExW.
*ImplWinFontData* pData = ImplLogMetricToDevFontDataW( pLogFont,
&(pMetric->ntmTm), nFontType)
pData->UpdateFromHDC(mhDC);*
Looks ok.
Unfortunately, *pData->HasChar(c)* always returns false even
*pData*contains the character *c*.
How do you know that pData contains c? If it returns false this is a
strong indication that it isn't there.
I don't know what's the problem. In addition, any idea to enable glyph
fallback under windows platform would be also highly appreciated
just as
done under Linux system leveraging fontconfig lib.
That's also quite interesting. Which Windows versions have fontconfig
nowadays? Who maintains the configuration data?
