Hi Diane,

I did some random typing in of Alt-key-plus-number-pad combinations to guesstimate the range of characters you should include in your regexp to check for word characters in the languages you list below. It looks like the extended characters all live in the 128 to 165 range (for example, Alt+128 is Ç, and Alt+165 is Ñ). So if you check for [a-zA-ZÇ-Ñ0-9] in your regexp, you should be covered.
