-call setlocale(LC_CTYPE, "") before nl_langinfo(CODESET) if the locale settings is (still) at "C" - otherwise the CODESET doesn't work -fix the type of the WACS_* symbols -- this needs to be cchar_t* -add safeguards where the return value of wcwidth() is used for loop counters or indexing -- it can be -1 -use more common code in the widechar support case -- in particular let the wchar functions do the work even if chtype ones were called -implement wcursyncup/wsyncup/wsyncdown -somewhat experimental: allow ACS_* variables to refer to WACS_* table entries -- this way, programs using the old chtype using API can use UTF8 line drawing on terminals which support UTF8 but not ACS switching -fix some logics bugs in UTF8 recognition and ALTCHARSET handling
