Hi, In order to enable glyph fallback under Windows platform, a class WinGlyphFallbackSubstitution inherited ImplGlyphFallbackFontSubstitution is created as the class FcGlyphFallbackSubstitution under Linux system. 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);* Unfortunately, *pData->HasChar(c)* always returns false even *pData*contains the character *c*. 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. Thanks in advance. Best regards, Yanmin Jia
