Juraj Lonc commented on PDFBOX-1473:
------------------------------------
Yes. But you have to remember that any sequence of operators and operands which
comes to CharStringConverter must be already "inflated" (subrs replaced). If
there is any subr command in that sequence then exception should be thrown.
You are right, handling of subr commands in CharStringConverter is obsolete and
not necessary.
If you remove handling of subr commands than CharStringConverter does not need
fontGlobalSubrIndex/fontLocalSubrIndex.
Type1CharStringParser should be fixed the same way.
