ord

  • ord EXPR

  • ord

    Returns the numeric (the native 8-bit encoding, like ASCII or EBCDIC, or Unicode) value of the first character of EXPR. If EXPR is an empty string, returns 0. If EXPR is omitted, uses $_ . (Note character, not byte.)

    For the reverse, see chr. See perlunicode for more about Unicode.
