Big conversion to wide characters and UTF-8 support.

This is incomplete. There are too many dependencies on
wide character support from the C stream I/O library,
and implicit use of some encoding which may not be UTF-8.
The regex code does not handle wide characters properly.
Character type is still int in some places, rather than wchar_t.
Test suite passes though.
