Unicode::UCD

📦 std

Unicode::UCD - the Unicode Character Database: what perl knows about each character, block and script.

use Unicode::UCD qw(charblock charinfo);

my $ci = charinfo(0xE9);
printf "Unicode %s | %s | %s, class %s\n", Unicode::UCD::UnicodeVersion(),
    charblock(0x263A), $ci->{name}, $ci->{category};
# Unicode 17.0.0 | Miscellaneous Symbols | LATIN SMALL LETTER E WITH ACUTE, class Ll

charinfo, charblock, charscript, charblocks, charscripts, charprop, prop_invlist, casefold, casespec, num and the rest are Unicode/UCD.pm 0.83’s own Perl, unchanged, over the data of the Unicode version perl 5.44 was built with (17.0.0) whatever the host has installed.

Upstream reads three of its tables - the Unicode version, the block list and the special casing rules - from files along @INC (unicore/version, unicore/Blocks.txt, unicore/SpecialCasing.txt). pperl stores them in the binary when it is built and hands them to UCD.pm when it loads, so nothing is read from disk.

Differences from upstream

None in behaviour.
