First - I'm extending

logbox.system.logging.appenders.FileAppender

and wish to have non-alphanumeric characters in the file name. However,

FileAppender

strips these out as part of its init method. Can a new function be added to that component to do the sanitization so that my extending component can override the default behavior? Alternately, allowing characters like ".", "-", and "_" feel like a good idea to me.

Probably best to just put in a change to the core since that seems like a reasonable change
