[For others: trying to list all page titles that contain any characters, *other than*: alphanumeric, spaces, underscores, dashes]

I'm seeing the same. I went to this regex chat and asked them for a regex, which worked on the regex tester http://regexpal.com/ but not on the bot :-(.

python pagegenerators.py -titleregex:.*[^\w\s-].*            ...  - [1]
#1 hits all pages including ones that only have that set of characters, for example its also showing up "Apple".
