Yes, this has been asked before - but I don't remember what the answer was.
The easiest way would be to check for non-alphanumeric chars using a
regex. If you find any, tell the user to use plain text editor.
You could use a regex to strip non-alphanumeric characters, but this
might have some problems. For instance, what happens if you have a
control sequence which happens to contain a character - i.e. 0x010231?
The 0x42 would be taken as the character '1', even though it's part of a
control sequence. But you could clean it up fairly well this way.
Try googling this newsgroup for something like "MS WORD". It's been a
few months.
