STINNER Victor <[email protected]> added the comment:
Using curses_unicode.patch:
- without ncursesw: addch('é') raises an OverflowError because
'é'.encode('UTF-8') is 2 bytes and not 1 byte
- with ncursesw: the charset is displayable character depends on the locale
encoding (e.g. € cannot be printed with ISO-8859-1 locale encoding)
- with ncursesw: any character can be printed with a UTF-8 locale encoding
(including non-BMP characters: U-10000..U+10FFFF)
It would be possible to support multibyte encoded character (like é in UTF-8)
for addch() by calling addch() multiple times, one per byte, but I would prefer
to keep _curses simple and not workaround libncurses limitations (bugs).
