Invisible 0xFFFD character error in script (stops compilation)

I have looked at the threads about this problem but I still can’t solve it.
How do I search for 0xFFFD to enable me to delete it and where has it come from ?
I think it may have come from copying and pasting a script from a web site perhaps ?

Thanks

This bug has been reported (case number 378119) but not fixed yet. In the meantime, you will need to use an editor that can search for this character and remove it from the script.

If the script is relatively manageable in size you can just type it into a new file yourself; that’ll remove the character. If not, try copying and pasting your code into an editor with support for large character sets, and it might show up (0xFFFD is used to replace characters that aren’t supported in your charset). You might try Notepad++, though I can’t offer any guarantee that it will help.

Thanks, good to know it’s not me being dumb !
