That's a nice method, but I recommend not to use it for getting actual glyph
metrics of a whole string. As it moves characters out of the context, the method
is unlikely to return the correct metrics for certain scripts like arabic, in
which
the rendered character metrics depends on the surrounding string context
(storage vs. represantation form).
Anyway, well done.
