Hi,
I want to make sure that respondence only may write one word in each response box. So i've been using this:
/^[-\w]+(?:\W+[-\w]+){0,1}\W*$/ from the manual www.limesurvey.org/manual/Using_regular_expressions .

However, it does not work for the swedish letter å ä and ö. That is, respondents are no allowed to write those letters.
I am not sure what this regular expression does; but would it not be best to have a regular expression that does not allow the space? And in that case how would it look.

Thanks
