+ /* Note: We do not use the Xmb*() functions and XFontSets.
+ Those functions are generally losing for a number of reasons:
+
+ 1) They only support one locale (e.g. you could display
+ Japanese and ASCII text, but not mixed Japanese/Chinese
+ text). You could maybe call setlocale() frequently
+ to try to deal with this, but that would generally
+ fail because an XFontSet is tied to one locale and
+ won't have the other character sets in it.
+ 2) Not all (or even very many) OS's support the useful
+ locales. For example, as far as I know SunOS and
+ Solaris only support the Japanese locale if you get the
+ special Asian-language version of the OS. Yuck yuck
+ yuck. Linux doesn't support the Japanese locale at
+ all.
+ 3) The locale support in X only exists in R5, not in R4.
+ (Not sure how big of a problem this is: how many
+ people are using R4?)
+ 4) Who knows if the multi-byte text format (which is locale-
+ specific) is even the same for the same locale on
+ different OS's? It's not even documented anywhere that
+ I can find what the multi-byte text format for the
+ Japanese locale under SunOS and Solaris is, but I assume
+ it's EUC.
