this is the reason why we disallow it. If it's not found on your English keyboard, then it's more than likely to be blocked.
I wish there was a list, but I don't have one. Sorry Toni, I know it's a pain sometimes, but how often do you actually copy and paste quotes that have these symbols?
I know it's not intuitive, but perhaps pasting in to Microsoft notepad first before pasting in the forums? The special characters where causing problems in our system and thus we made the decision to disallow it. So I hope you understand.
There have been a number of times when I have copied/pasted a quote from a website and after trying to 'submit post' a red warning comes up that I have used non-English symbols not recognized. Trying to figure out which symbols the filter doesn't like is pretty frustrating because it sometimes is nothing more than a footnote number that I have to backspace out of the quote or a ridiculous almost impossible to notice Windows character map item such as a 'true' "1/2" symbol.
Is there any way that this software could perhaps highlight what it doesn't like when the warning comes up so people don't have to read every single word of their posts again and try to figure it out?
