Three and a half years later (yeah, I got distracted), I've finally
learned enough to understand and appreciate what you said there.
So if you don't detect the missing glyph until building the subset, that
means you can detect it then. For efficiency, I can understand why it
might be deferred, allowing and assuming the user specifies the right
font for the particular characters.
But this user doesn't always know. Now I could make an assumption about
certain character ranges being in certain fonts, but is there a way I
can ask reportlab "Does this character exist in this font?"
