Yes, it's equivalent to an ASCII interpretation.
Worth noting is that
- using hex does not automatically mean that we are dealing with unicode. E.g.
#20 shall be used for encoding a space within a name where prior to PDF 1.2 #
alone was used as a placeholder
- after decoding the hex code a name might be in UTF-8
- the bytes making up the name shall be used as the names value and not the
string representation.
There is also an error in above string - which I'll correct (I was using a
comma instead of the quotation mark)
According to Extented ASCII Table ISO-8859-1:
#82 is {{‚}} {{Single low-9 quotation mark}}
#96 is {{–}} {{En dash}}
Details in the PDF spec.
