Yes, there is. If you revert that patch "+    } else if (is_std_t1font(fm))"
then specified PK font with enc file via \pdfmapline{} will be ignored,
pdftex fallback from \pdfmapline{} definition to PK font *without* any
enc file.

So in result PDF file \ToUnicode entry would be missing and enc file in
\pdfmapline{} ignored.

It is really needed to call set_truetype() or set_opentype() or
set_type1()? Seems that no. All code tests if is_truetype(),
is_opentype() or is_type1(). And setting type1 for PK/type3 font is 
incorrect and just cause dropping all PK/type3 fonts as they do not have
(for obvious reason) specified PS font basename.

What is possible is to introduce set_type3() and is_type3() macros and
then set last fallback to set_type3().
