That's not what the English says, and I'm surprised if that's what a literal translation into French means.

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. Richard.
