81 /* Note: We do not use the Xmb*() functions and XFontSets.
|
|
|
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.
|
|
|
90 2) Not all (or even very many) OS's support the useful
|
|
|
91 locales. For example, as far as I know SunOS and
|
|
|
92 Solaris only support the Japanese locale if you get the
|
|
|
93 special Asian-language version of the OS. Yuck yuck
|
|
|
94 yuck. Linux doesn't support the Japanese locale at
|
|
|
95 all.
|
|
|
96 3) The locale support in X only exists in R5, not in R4.
|
|
|
97 (Not sure how big of a problem this is: how many
|
|
|
98 people are using R4?)
|
|
|
99 4) Who knows if the multi-byte text format (which is locale-
|
|
|
100 specific) is even the same for the same locale on
|
|
|
101 different OS's? It's not even documented anywhere that
|
|
|
102 I can find what the multi-byte text format for the
|
|
|
103 Japanese locale under SunOS and Solaris is, but I assume
|
|
|
104 it's EUC.

753 XOFFSET Number of pixels to be chopped off the left side of the
