Capture event on file upload to prevent illegal characters

Vote:
 
We have Epi 4.31. Many of our editors (more than 100) still uploads files to the file upload directory, with file names including "illegal" characters such as spaces or å, ä, ö. Even if we instruct them to not do so. We would like to do a function that takes care of the file upload event, to check if there are illegal characters in the file names, and then display an error message. Can this be done and what is the best way? We use some event handlers in global.asax for page saving and page updating etc, but I can not find events for when a file is beeing uploaded?
