How to know if a Unicode character is 'allowed' in 'Security Profile for General Identifiers' for PHP?
<p>This document <a href="http://www.unicode.org/reports/tr39/#General_Security_Profile" rel="nofollow">General Security Profile for Identifiers</a> says that for a Unicode character be eligible to be part of an identifier (among other conditions), it should have status 'allowed' here: <a href="http://www.unicode.org/Public/security/latest/xidmodifications.txt" rel="nofollow">xidmodifications.txt</a>. The character whose status are 'Restricted' are not eligible.</p>

<p>Is there a way in PHP 5 to accessing this property?
What I want specifically is: given a string know if all the characters are good ones for the Unicode Consortium.</p>
