John Hewson commented on PDFBOX-3403:
-------------------------------------
{quote}Couldn't in that case an empty encoding serve the extra needs?{quote}
No because we're talking about a font's built-in encoding which can never be
null, or empty, or missing. It must be there. If it's somehow not then PDFBox
would substitute a valid font file in its place. So at this point in the code,
the built-in encoding must be *something*. Also, for symbolic fonts without a
valid BaseEncoding, this is the encoding which we're going to actually use to
read from that font - so empty is not a useful value, as it means we can't
decode any of that font's text.
{quote}Ah, indeed. I was misled by the JavaDocs of the three-argument
constructor which also mentions Type 3 fonts.{quote}
Yes we do overload the constructors, so Type 3 code does call this, but it's
handled as a special case, the rules that apply there don't apply to non-Type 3
fonts.
