Unfortunately I still haven't tested it thoroughly, but I didn't want to leave this question open any longer. &nbsp;Thanks for your response!

<div class="content wysiwyg-content">
I'm currently strip all non-alphanumeric characters from a string in PHP like this:<br />
preg_replace(&quot;/\W/&quot;,&quot;&quot;,$st<wbr />rText)<br />
<br />
I'd like to change it so it doesn't strip spanish characters.<br />
<br />
FYI, my server's locale is english-us.<br />
<br />
The spanish characters I don't want to strip include:<br />
[ÁáÉéÍíÑñÓóÚúÜü«»¿¡€P]<br />
<br />
In hexadecimal they'd be:<br />
[\xC1\xE1\xC9\xE9\xCD\xED\<wbr />xD1\xF1\xD<wbr />3\xF3\xDA\<wbr />xFA\xDC\xF<wbr />C\xAB\xBB\<wbr />xBF\xA1\x8<wbr />0\x20A7]

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.
