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

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


SOURCE
       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)?                              (((c)&0x04)?6:5):4):3):2):1)
