|
|
|
82 Those functions are generally losing for a number of reasons:
|
|
|
83
|
|
|
84 1) They only support one locale (e.g. you could display
|
|
|
85 Japanese and ASCII text, but not mixed Japanese/Chinese
|
|
|
86 text). You could maybe call setlocale() frequently
|
|
|
87 to try to deal with this, but that would generally
|
|
|
88 fail because an XFontSet is tied to one locale and
|
|
|
89 won't have the other character sets in it.
|
|
3094
|
90
|
|
|
91 The following aren't true any more, but that doesn't make Xmb*()
|
|
|
92 usable. One wonders about Xft and Pango, etc, tho'. Except they
|
|
|
93 aren't cross-platform solutions. FMH, as jwz would say. -- sjt
|
|
|
94 [[
|
|
428
|
95 2) Not all (or even very many) OS's support the useful
|
|
|
96 locales. For example, as far as I know SunOS and
|
|
|
97 Solaris only support the Japanese locale if you get the
|
|
|
98 special Asian-language version of the OS. Yuck yuck
|
|
|
99 yuck. Linux doesn't support the Japanese locale at
|
|
|
100 all.
|
|
|
101 3) The locale support in X only exists in R5, not in R4.
|
|
|
102 (Not sure how big of a problem this is: how many
|
|
|
103 people are using R4?)
|
|
|
104 4) Who knows if the multi-byte text format (which is locale-
|
|
|
105 specific) is even the same for the same locale on
|
|
|
106 different OS's? It's not even documented anywhere that
|
|
|
107 I can find what the multi-byte text format for the
|
|
|
108 Japanese locale under SunOS and Solaris is, but I assume
|
|
|
109 it's EUC.

134 /* Notes on Xft implementation
|
|
|
135
|
|
|
136 - Xft Reloaded, v.4, uses a function like that in redisplay-msw.c to
|
|
|
137 handle all characters. However, instead of using an appropriate
|
|
|
138 character width for each run, it just uses UTF-8 for all runs. This
|
|
|
139 is not obviously a bad idea, but (for Han characters etc) the estimate
|
|
|
140 of TEXT_STORAGE allocation needed is (3 * len), and for characters not
|
|
|
141 in the BMP, it's (4 * len).
|
|
|
142 - With Unicode, we're no longer going to have repertoires reified as
|
|
|
143 charsets. (Not that we ever really did, what with corporate variants,
|
|
|
144 and so on.) So we really should be querying the face for the desired
|
|
|
145 font, rather than the character for the charset, and that's what would
|
|
|
146 determine the separation into runs.
|
|
|
147 - The widechar versions of fontconfig (and therefore Xft) functions
|
|
|
148 seem to be just bigendian Unicode. So there's actually no need to use
|
|
|
149 the 8-bit versions in computing runs and runes, it would seem.
|
|
|
150 - Mule won't "just work"; substantially more effort seems needed.
