Yes.  If font_driver->shape is implemented correctly,
font-shape-gstring should compose the given sequence with
multiple grapheme clusters.

But, I admit the above regexp is not optimal.  For
efficiency, the regexp should match only with a character
sequence that is composed into one grapheme cluster.
