There is no fix for supporting non-scalable PK fonts with enc file. 
Therefore I introduced this \pdfpkscalable boolean register.

Once PK font with enc file is defined in mapline it is used as scalable. 
You can check this fact by generating PDF file that it contains mapping 
for ffi ligature. Also check pdftex output that mapline was not ignored. 
Because if mapline is ignored, then pdftex automatically fallback to 
non-scalable PK fonts, but without enc file. And when pdftex ignore 
mapline it just show non-fatal warning and produce PDF file without 
errors. I was already hit by this behaviour that warnings from mapfile 
are non-fatal...
