Strip non-alphanumeric except spanish characters.

I'm currently strip all non-alphanumeric characters from a string in PHP like this:
preg_replace("/\W/","",$strText)

I'd like to change it so it doesn't strip spanish characters.

FYI, my server's locale is english-us.

The spanish characters I don't want to strip include:
[ÁáÉéÍíÑñÓóÚúÜü«»¿¡€P]

In hexadecimal they'd be:
[\xC1\xE1\xC9\xE9\xCD\xED\xD1\xF1\xD3\xF3\xDA\xFA\xDC\xFC\xAB\xBB\xBF\xA1\x80\x20A7]
