------- Comment #3 from pcarlini at suse dot de 2007-10-28 09:53 ------- Cout & co by default aren't converting streams, they are synced char-by-char with stdio, therefore cannot be expected to work with UTF-8 in any meaningful way. If you call sync_with_stdio(false) at the beginning of your program and then imbue the proper locale, things will work with any encoding >= 0 locale, UTF-8 or other, if you make sure to use wchar_t as your internal representation (we do not provide char <-> char codecvts).
Note that a lot about locale and streams is implementation defined in the current standard and we consider our design choices (sync with stdio by default, required in the standard, then a converting stream if syncing is disabled) only a very good compromise. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33852
