Yes.

T1 and TTF.

Just single byte.

No. You can have the same font with different differences array. iText
can't (easily) do it.

PdfContentParser.

See above.

If needed.

That font or other if you are doing font replacement.
The bottom line is that I'll include your code in iText and hope that it
will be improved later, by you or someone else.
