I'm really unclear why this should be used by any rational person, but if it
works for you I see no reason not to use it.

I am puzzled by the patch though.

Should we not be turning off all of the subsetting code?

It just happens that we currently preset the first subset to be the standard
ascii subset (in the default case) so perhaps this won't work if two or more
subsets are required.

I'll try later with some tests high order arial characters.
