OK, I'll lift my hands up and admit that it is/was just a con
trick. But you'd have to admit that, for those who don't realise it, that the end results are seemingly the achievement of the impossible.
Anyhow, this got me thinking and I was wondering how I could give a folder a name consisting of characters that couldn't normally be used /?<>\:*|"^
This led me to the creation of this Tutorial: Private Character Editor
By following the method I described there, I copied the characters into the Private Character set and used them to actually name the folder. So what you're seeing is a folder with that name consisting of copied characters that are identical to the originals but with a different unicode assigned to them.
