NAME

Unicode::Properties - find out what properties a character has

SYNOPSIS

    use Unicode::Properties 'uniprops';
    my @prop_list = uniprops ('☺'); # Unicode smiley face
    print "@prop_list\n";

prints

    InMiscellaneousSymbols Any Assigned Common

You can then use, for example, \p{InMiscellaneousSymbols} to match this character in a regular expression.

FUNCTIONS

uniprops

Given a character, returns a list of properties which the character has.

matchchars

   my @matching = matchchars ($property);

Returns a list of all the characters which match a particular property. If $property is not found in the list of possible Unicode properties, it treats it as a regular expression.

BUGS

Data source

This module uses a list taken from the "perlunicode" documentation. It would be better to use Perl's internals to get the list, but I don't know how to do that.

Perl & Unicode version

Depending on your Perl and Unicode version, you'll get different results. For example "Balinese" was added in Unicode version 5.0.0, so if you are using Perl 5.8.8 unpatched, your Unicode version is 4.1.0 so you won't get "Balinese" in the results list.

Also, I don't know the behaviour of Unicode versions other than 4.1.0 and 5.0.0, so this module only covers those two. I couldn't get Perl 5.8.5 to install on my computer, so I've set the minimum version to 5.8.8 for this module.

SEE ALSO

The "uniprops" script in Unicode::Tussle

This script was written because the author (Tom Christiansen) was dissatisfied with Unicode::Properties. Unfortunately, it uses the same method as this module, of parsing the Perl documentation to get the information. It only works for Perl versions 5.12 or 5.14.
