simple example of 2 download fonts

Kens analysis:

So the first string (in the lighter weight font) "Statement activity current as
of August 19, 2010" gets encoded as you would expect. When we switch fonts, any
text which is at a position which hasn't already been used gets encoded where
you would expect, so *some* of the glyphs end up encoded normally. Glyphs whose
encoding position has already been used get moved to the first empty slot.

... details elided ...

Eventually, as we fill the font up with glyphs from numerous different input
fonts, the output font becomes full and we start a new output font. I think
this could lead to us loading the same characters into different fonts.
