[HECnet] Arabic / Unicode support on VMS?

Does VMS support Arabic text in the console (VT-series terminals etc) or graphical modes (X11)? In about 1983, I did some work on VMS 3.x systems in Riyadh. The user terminals were Tandberg 2200 family devices with Arabic language support. I don't recall there being anything special about the installed VMS: it had no significant localizations in terms of system messages, etc. We were able to do mixed English and Arabic text on these terminals using standard system utilities (EDT), COBOL applications and the Cincom Total database. The terminals operated on a set-shift model, and it seems like maybe the | character was the shift. Everything was single-byte character sets. IIRC the terminals dealt with the Arabic positional shifting character forms. I suspect this isn't exactly what you're looking for, though. De
