I use a mac, so I don't notice this, but it seems at least one PC user of my forum is having trouble with 'alt characters'.
Here are some examples
If you are a PC user, it seems if you enable numlock on your PC, then hold the alt key and type those numbers above, you get those special characters. They have recently stopped working...but it seems, only on PHPBB...(and I have not done an upgrade!)
Does anybody have any thoughts on this?
