              The file in question uses an undocumented Encoding type for the Arabic glyphs. The encoding format is as follows:

              9 0 obj
              <<
              /Type /Encoding
              /Differences
              [ 0 /uni060C
              1 /uni061B
              2 /uni061F
              3 /uni0621
              ...
              233 /uniFEF5
              234 /uniFEF6
              235 /uniFEF7
              236 /uniFEF8
              237 /uniFEF9
              238 /uniFEFA
              239 /uniFEFB
              240 /uniFEFC
              241 /uniFEFD
              242 /uniFEFE
              243 /uniFEFF ]

              There is no mentioned of character names /uniHexCode in the PDF specification. If I were to guess this is a just format used by SAP. I've looked up the mappings 164->/uniFEB0 and the mapping appears to be valid, and corresponds to the character 'ARABIC LETTER ZAIN FINAL FORM' I need to figure out a way to detect and assign the correct glyph for this undocumented format.
