At times when issuing an output (OTF Data) print some characters appear as # and not the desired one.
Generally the only solutions possible are via cascading fonts (812821) or UPE solution (1812076).
Using an example text see the following extracted OTF data:
ST0188044Adresse Usines d#envoi
The 2019 character is not suppported in the HP device type's character set (Character set: 1116 Printer HPLJIIID ISO 8859/1 (Latin 1).
This is correct and thus would not allow the character to be printed.
Also for reference. http://www.unicode.org/charts/PDF/U2000.pdf
Do not that tt is correct that the cascading fonts device type will not work via method C (only via G and S possible..
