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.

    If NUMBER is omitted, uses $_ .

    For the reverse, use ord.

    Note that characters from 128 to 255 (inclusive) are by default internally not encoded as UTF-8 for backward compatibility reasons.

    See perlunicode for more about Unicode.
