invalid characters detected in character description

[PzKpfWg]

Hey guys.

I'm trying to sell a character and I can't complete it because i get this message: Invalid characters detected in char description.

Here's the description: Very close to level 76(less than 1 bar)
Fully Rested
Dual spec. Feral and Restoration (pve). Leveling gear for both
225 Riding, slow fly mount
417 Herbalism and 341 inscription. Various northern herbs. 5 books of glyph mastery

Can someone kindly point out the invalid characters?

Much appreciated.

This happens when you use special characters, just don't use any special characters other than full stops, apostrophes etc
