Special characters in filenames

[kapler]

1.4 had no problem with including the characters '(' and '^' in my filenames.
1.5 seems to not accept them into the database.  Is there any way to change this?

Not without editing core files and allowing security holes to be opened.

Thanks.
Considering my app is meant for third-world computing, I should adjust and only use _ and -, as advised.
