Invalid characters for filename are incomplete

[anneangersbach]

I stumbled across this line because we had to do an overlay in our project for it. I recognised that not all invalid characters for windows are removed (<, >, ").
I want to suggest changing this to a whitelist instead, since not only are there invalid characters that remain, but also the location of valid characters that make them invalid filenames could be an issue (e.g. space or dot at the beginning or end of a filename).
