I’m not sure if this is a bug.
How to reproduce
Create a new entry with the title with a ‘+’ sign somewhere
Entry is created and ‘+’ successfully displays
Edit the entry (notice that the ‘+’ is now missing)
Save the entry
What is expected
Title should not be changed.
What happens
Title is now missing the ‘+’, presumably because the display on the edit page screws up.
I haven’t tested for other characters, but is this a bug? Or is there a white/black list somewhere where ‘+’ signs are being excluded?
Thanks.
