(xfont_has_char): Special handling of `ja' and `ko' adstyle.

parent b840b299
2009-04-16 Kenichi Handa <handa@m17n.org>
* xfont.c (xfont_has_char): Special handling of `ja' and `ko'
adstyle.
* xftfont.c (xftfont_has_char): Special handling of `ja' and `ko'
adstyle.
* ftfont.c (Qja, Qko): Don't make them static.
(enum ftfont_cache_for): New enum.
(fc_charset_table): Undo the previous change.
(ftfont_get_latin1_charset): Delete it.
(ftfont_pattern_entity): Check cache by ftfont_lookup_cache. Set
FONT_SIZE_INDEX of the entity to 0 for a scalable font. For a
non-scarable font, try to get AVERAGE_WIDTH.
(ftfont_lookup_cache): Argument FOR-FACE is changed to CACHE_FOR.
Change ft_face_cache from a list of a hash-table. Don't check
`ja' and `ko' adstyle here.
(ftfont_get_fc_charset): Call ftfont_lookup_cache with
FTFONT_CACHE_FOR_CHARET.
(ftfont_get_charset): Undo the previous change.
(ftfont_open): Call ftfont_lookup_cache with
FTFONT_CACHE_FOR_FACE.
(ftfont_close): Likewise.
(ftfont_has_char): Special handling of `ja' and `ko' adstyle.
* font.c (font_sort_entites): Change the meaning of the arg
BEST-ONLY. Don't optimize for VEC of lenght 1.
(font_select_entity): Just return the value of font_sort_entites.
* xfaces.c (merge_face_vectors): Reflect font properties in
to[LFACE_FONT_INDEX] to the other face attributes. Don't call
font_clear_prop if a face attribute doesn't change.
* charset.h (charset_ksc5601): Extern it.
* charset.c (charset_ksc5601): New variable.
