Where is that quoted from? I was not aware that there was a difference between "byte-oriented" and "wide-oriented" streams. I thought getwc did the conversion between LC_CTYPE charset and wide-char itself, though I see the getwc manpage only says that "it is reasonable to expect" this in "the absence of additional information passed to the fopen call". This Debian i18n page seems to imply that it should work (see 6.3), and it's what I was going from: http://www.debian.org/doc/manuals/intro-i18n/ch-locale.en.html But if there is a difference, then the iconv sample on that page (see 6.5) could be a better choice than hardcoding the UTF-8 conversion, and (therefore) only working in a UTF-8 charset environment. (Plus, you don't know what the user will set LC_CTYPE to; it might be utf8, it might be utf-8, it might be UTF8, and any of these will break the patch.)
