Hmm, I do understand Chinese, and I can confirm that the content
of RGui-zh_CN.po in R 2.4 is in utf-8 rather than CP936.

I can also confirm that CP950(big5) for RGui-zh_TW.po is correct, and
CP932(shift-JIS) for  RGui-ja.po is also correct. (so you'll need to 
find some korean to verify CP949 for RGui-ko.po).

However, the fix is slightly "asymmetric". Out of ru, zh_CN, zh_TW,
ja, ko, only ru in R-2.4.0/po/*.po is in localised encoding,
(the others 4 in UTF-8), whereas RGui-*.po, after the fix, all
are in localised encoding except RGui-zh_CN.po .

I would propose correcting the encoding of the *content*, rather
than the charset tag, so that Rgui-* all uses localised ones (CP932, 
CP936, CP949, CP950). That should be better for older windows...

Just my two cents/pennies...
