handling on Unicode, UTF-8 and localized 8 bit encodings

NAME
CHAR_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

/* 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)
#ifdef WIN32
#define UNICODE_CHAR_SIZE(c)    sizeof(UNICODE_CHAR)
