I want to use oriental languages in troff but I don't want to reinvent the wheel. Rather, I want to ask if there is any way I can control standard C/A/T troff or device independent troff to use my character set, specifically mycharacter set is going to be multibyte. I guess it requires at least some knowledge in troff font format. Any ideas? Thank you. -- WAN, Nga Ting Alex | Internet: Department of Computer Engineering | umwan010@ccu.umanitoba.ca University of Manitoba, Canada R3T-2N2 |

It's not possible with any existing version of troff because they're all 8-bit (indeed, most are 7 bit). That being said, you can introduce a lot more if you're willing to use \(xx sequences. C/A/T troff can only be made to extend its character set thru the use of psroff 3.0 (Transcript won't). However, it's not likely to be reliable enough for any serious use. Troff doesn't know about fonts directly. It has font metrics files, and the troff-to-whatever-printer filter *may* have to deal directly with fonts rather than simply asking the printer for them. The width table format is relatively simple. Consult the width tables that come with your troff. Though, if you have C/A/T troff, you'll need psroff3.0's width table handling. -- Chris Lewis; clewis@ferret.ocunix.on.ca; Phone: Canada 613 832-0541 Psroff 3.0 info: psroff-request@ferret.ocunix.on.ca Ferret list: ferret-request@ferret.ocunix.on.ca

There was an implementation by UNIX Pacific, but
just for one of the Japanese character sets.
It's based on our DWB, but uses as special variable-
byte encoding. It can be purchased from UNIX Pacific,
I believe:
USL Pacific - tel: 81-2-5484-8605
fax: 81-2-5484-8606
Recent Research efforts in Bell Labs are based on UNICODE,
and we are currently considering whether to offer a
UNICODE version on DWB. This would cover Chinese, Korean,
and several hundred other languages, including many
Indian dialects.
The current DWB available from USL and NCR (3.2)
supports only Western European languages, as per
ISO 8859-1.
