NAME¶

char2uni - handling on Unicode, UTF-8 and localized 8 bit encodings libAfterImage/CHAR_SIZE

NAMECHAR_SIZE¶

- Convenient macro so we can transparently determine the number of bytes that character spans. It assumes UTF-8 encoding when I18N is enabled.

SOURCE¶

/* size of the UTF-8 encoded character is based on value of 
 * the first byte : */
#define UTF8_CHAR_SIZE(c)   ((((c)&0xC0)==0xC0)? \
                             (((c)&0x20)? \
                             (((c)&0x10)? \
                             (((c)&0x08)? \
