---------------------------------------------------------------
The JVM is likely to just optimize away those ArrayLists completely. Remember,
small, short-lived allocations perform very well with GC. Unless you have a
concrete performance issue, I'd recommend designing a clean API first.
You seem to be saying that you've tightly coupled CmapSubtable with
PDCIDFontType2Embedder, but this isn't a desirable thing. CmapSubtable is a
public API and needs to expose something clean and general purpose -
irrespective of what PDCIDFontType2Embedder wants to then do with that result.
You're implying that it's a just a private API... but it's not.
Again, this method doesn't even necessarily return Unicode characters.
