Hello. Would anybody explain me please, why __jp2uc() call is needed in newlib-1.11.0/newlib/libc/ctype/iswalpha.c, lines 80, 85, 90. As I understand, this is a conversion from JIS, SJIS and EUCJP to Unicode. But, wide characters are independent from any encoding type and are usually already represented by Unicode. Thanks. Artem.
