Entries with "(" ")" doesn't working

Hi,
very nice and most perfectly working plugin!

but on my site i have some not working entries like this:
“Tree (bs)”

It seems to be a problem with the “(” “)”, because if i write without it, it works fine.
Please add support for this case.

Thank you for Help and this great Plugin
