  • 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. Note that characters from 128 to 255 (inclusive) are by default not encoded in UTF-8 Unicode for backward compatibility reasons (but see encoding).

    If NUMBER is omitted, uses $_ .

    For the reverse, use ord.

    Note that under the bytes pragma the NUMBER is masked to the low eight bits.

    See perlunicode and encoding for more about Unicode.
