Escaping the Filter command's wildcards

Hi Paul,

I see what you mean. You weren't looking for a solution, just for more 
trouble :-)

I tried several special characters and they can all be used to filter 
lines with the same workaround. Unfortunately, many of those special 
characters have no effect, because regex isn't fully supported by the 
filter command, as Pete mentioned already. Therefore I wonder why we 
need to escape the question mark. That seems inconsistent to me.

Best regards,

Mark Schonewille
