post title characters

[kenfuzed]

Is there a rewrite or some way to filter special characters from thread titles? If there is already a vBulletin control for this I apologize, but I've yet to locate it.

Basically what I'd like to do is delete any non a-z characters that get typed into thread titles. vBSEO already rewrites this in the URL but not the actual title. Example; if someone titles their thread "widget!?" I'd like to rewrite this as "widget". This is mostly for asthetics, since it drives me crazy to see all these characters appear in my navbar message.

Also while I don't know that much about SEO, I would think that both words (widget!? and widget) could be indexed differently. Regardless, I'd just rather not see non-alpha characters appear mid-sentence in a description.
