Remove the platform-dependent type xchar

File fl_utf8.h defines the xchar type with a platform-dependent value (wchar_t or unsigned short).
But it is used exclusively by WIN32 code (0 use in cross-platform code, 0 use in APPLE
or in USE_X11 code).
Thus, we can just get rid of this type and replace it by wchar_t where it is used.
