Update UTF-8 base code
UTF-8 encodes characters in one to four bytes (since 2003). Because 0 is a valid code point, the decode function utf8_ord() should return -1, not 0, on error. As a consequence utf8_width() should return 0 for a continuation byte (as it did previously). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
