NAME

Unicode::Security - Unicode security mechanisms

SYNOPSIS

use Unicode::Security qw(
    confusable restriction_level whole_script_confusable
    mixed_script_confusable mixed_script mixed_number
);

$truth = confusable($string1, $string2);
$truth = whole_script_confusable($script, $string);
$truth = mixed_script_confusable($string);
$truth = mixed_script($string);
$truth = mixed_number($string);
$level = restriction_level($string);

DESCRIPTION

Implements the Unicode security mechanisms as described in the Unicode Technical Standard #39.

FUNCTIONS

confusable

$truth = confusable($string1,  $string2)

Returns true if the two strings are visually confusable.

whole_script_confusable

ws_confusable

$truth = whole_script_confusable($script, $string)

Returns true if the string is whole-script confusable within the given script. Returns undef if the string contains multiple scripts.

mixed_script_confusable

ms_confusable

$truth = mixed_script_confusable($string)

Returns true if the string is mixed-script confusable.

skeleton

$skel = skeleton($string)

The skeleton transform is used internally by the confusable algorithm. The result is not intended for display, storage or transmission. It should be thought of as an intermediate processing form, similar to a hashcode. The characters in the skeleton are not guaranteed to be identifier characters.

restriction_level

$level = restriction_level($string [, $non_id_regex])

Returns the restriction level (0-5) of the string. The default Identifier Profile matches against \P{ID_Continue}. If you want to use a different Identifier Profile, you can pass in an optional regular expression to test for non-identifier characters.

soss

%soss = soss($string)

The set of Unicode character script names for a given string. Used internally by the restriction level algorithm.

mixed_script

$truth = mixed_script($string)

Returns true if the string contains mixed scripts.

mixed_number

mixed_num

$truth = mixed_number($string)

Returns true if the string is composed of characters from different decimal number systems.
