toggleCase stuff: remlaced Title Case with 'First capital, rest lowercase', fixed UT_UCS_isspace() for wider Unicode compliance.
UnixEncodingManager: a change that makes AbiWord more usable under utf-8 locale with non-English 8-bit charset (e.g., cs_CZ.utf-8); this fix is not perfect, but until gtk 2 it will have to do. Also, there is a chance that it might break some Unices on account of getenv and setenv -- will deal with it if/when it happens. Tomas
