# Unicode

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

libAfterImage/CHAR_SIZE

- NAME

  CHAR_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)? \
                                   (((c)&0x04)?6:5):4):3):2):1)
      #ifdef WIN32
      #define UNICODE_CHAR_SIZE(c)    sizeof(UNICODE_CHAR)
      #endif
