NAME

P5chr - Implement Perl 5's chr() / ord() built-ins

SYNOPSIS

use P5chr; # exports chr() and ord()

my $a = 65;
say chr $a;

$_ = 65;
say chr();   # bare chr may be compilation error to prevent P5isms in Perl 6

my $a = "A";
say ord $a;

$_ = "A";
say ord();   # bare ord may be compilation error to prevent P5isms in Perl 6

DESCRIPTION

This module tries to mimic the behaviour of the chr and ord functions of Perl 5 as closely as possible.

ORIGINAL PERL 5 DOCUMENTATION

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.

        Negative values give the Unicode replacement character
        (chr(0xfffd)), 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.

ord EXPR
ord     Returns the numeric 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".
