    chr NUMBER
    chr     Returns the character represented by that NUMBER in the
            character set. For example, "[chr(65)](https://www.chedong.com/phpMan.php/man/chr/65/markdown)" is "A" in either ASCII or
            Unicode, and [chr(0x263a)](https://www.chedong.com/phpMan.php/man/chr/0x263a/markdown) is a Unicode smiley face.

            Negative values give the Unicode replacement character
            ([chr(0xfffd)](https://www.chedong.com/phpMan.php/man/chr/0xfffd/markdown)), except under the bytes pragma, where the low
            eight bits of the value (truncated to an integer) are used.

            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.
