Hello all on freebsd-i18n,
Sorry first for someone may receive this letter twice.
I have tried to make a new locale setting (specifically, a LC_CTYPE
file) which is of EUC encoding, but it didn't work. After dumping codes
of some multibyte strings and their corresponding widechar strings, I
found only one of four codesets breaks - and it's byte length is 4,
which is lesser than the hard-coded length in euc.c (__mb_cur_max = 3).
This confuses me, does EUC really limit byte length of its codeset to 3?
I have made a patch to let this locale work (listed below), but if it
breaks something please let me know. Thank you!
Regards,
Yong-Jhen.
