chr

  • chr NUMBER
  • chr

    Returns the character represented by that NUMBER in the character set. For example, chr(65) is "A" in either ASCII or Unicode, and chr(0x263a) is a Unicode smiley face (but only within the scope of a use utf8 ). For the reverse, use ord. See utf8 for more about Unicode.

    If NUMBER is omitted, uses $_ .
