Re: [ft-devel] Encodings supported by PCF

[Alexei Podtelezhnikov]

I've got a downstream report that a PCF font is not showed in
gnome-font-viewer (see
https://bugzilla.redhat.com/show_bug.cgi?id=1451795).

After some debugging I've found that since the gnome-font-viewer uses
FT_Get_First_Char() and FT_Get_Next_Char() it needs a charmap defined in
its FT_Face but the font doesn't have one since the encoding is
FT_ENCODING_NONE. The font has CHARSET_REGISTRY "ISO646.1991" and
CHARSET_ENCODING "IRV" which seems to be ASCII basically.

 

IRV stands for International Reverence Version, a variant of ISO646 identical to ASCII, see https://en.wikipedia.org/wiki/ISO/IEC_646 .

My question is whether the encodings recognized as Unicode in
PCF_Face_Init() could be extended by this encoding?

Why not?
