I have fixed UT_UCS_tolower and UT_UCS_toupper as well as UT_UCS_islower and UT_UCS_isupper so that they should now work over the entire UCS-16 range. Also fixed couple of bugs in fv_View::toggleCase, and an incorrect assert in xap_UnixFontManager.cpp
Tomas modified: ut_string.cpp, ut_case.h, xap_UnixFontManager.cpp, fv_View.cpp
