The unit test for mbrtowc uncovered four different bugs in various systems of
the system-provided mbrtowc function.
mbrtowc was introduced to allow traversing strings that are stored in
non-contiguous memory blocks. This essential functionality does not
work on AIX 5.1, HP-UX 11.11, OSF/1 5.1, Sol
t)(-2). But glibc returns 0. Hmm...
- glibc's mbtowc() implementation for UTF-8 is buggy.
