• 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
  #define CHAR_SIZE(c)            1
