That's not what the English says, and I'm surprised if that's what a
literal translation into French means. I do half suspect that he
actually tried to post a lone surrogate.

I'd much prefer to be able to delete the first character of a grapheme
cluster. It's annoying to have to retype 4 characters because one's
mistyped the first of the 4 characters in a grapheme cluster. Removing
the restriction would be much more useful.
