I always thought that was how it was prn too. I like it. However, I think it could be somewhat troublesome as a written character name, or with new acquaintances .. because of the tendency to prn it with a SH sound (due to similarity of
Charlotte,
Charlene,
Charmaine) or a hard CH like
Charlie. Also, people hearing it only would tend to think of
Carmine.
