Filter and the Question Mark (escaping ? in regex)

[Malte Brill]

Hi,

I got a var tText that contains:

asdf
jkl?
bcdk

I want to do something like this

filter tText with "*\?*"

which should leave me with only jkl?. This does not appear to work. Any pointers on how to correctly escape the question mark greatly appreciated.

Cheers,

Malte
