No CWS, I filed a issue just now. The issue number is 101552. > > > To implement the class WinGlyphFallbackSubstitution, It's necessary to >> know if >> a character is contained in a given font.

Which Windows versions have fontconfig > nowadays? Who maintains the configuration data? Maybe you misunderstand what I said. I mean that fontconfig was used to improve glyph fallback just under linux system. A similar way could be considered under windows system, certainly there is no fongconfig available under window.[?] > > > --- > Herbert Duerr > du...@sun.com > > > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@gsl.openoffice.org > For additional commands, e-mail: dev-h...@gsl.openoffice.org > > Yanmin Jia
