Based on Dan's email:

glad to hear that you're getting ready to upload with gwtoolset. sorry that you're running into an issue. at the moment the following characters are replaced with a '-' in a title without a method to override any of them:

'#','<','>','[',']','|','{','}',':','¬','`','!','"','£','$','^','&','*','(',')','+','=','~','?',',',';',"'",'@'

this list was comprised based on several wiki articles:

• https://commons.wikimedia.org/wiki/Commons:File_naming
• http://en.wikipedia.org/wiki/Wikipedia:Naming_conventions_(technical_restrictions)
• http://www.mediawiki.org/wiki/Help:Bad_title
• http://commons.wikimedia.org/wiki/MediaWiki:Titleblacklist

i'm not sure who would or what process would “approve” the issue of relaxing that restriction to also allow the characters: '(',')',','. maybe someone else on this list would know. my guess is that if the commons admins and community are okay with it, then we can go ahead and allow those characters, but i don't know how that's done. maybe via an rfc or village pump article with votes ...

We should have a look at this at the hackathon and maybe publish a page on Commons with technical details that can be reused by other tools (like Pywikibot).
