Re: [9fans] plan9port troff - \(sq character

[arnold@skeeve.com]

It looks like p9 troff is using unicode characters for those
and the Lucida fonts. groff seems to be doing something different.

I'm using plan9port on Linux and evince to view the postscript.

I can send you the .ps file off list if interested.

Thanks,

Arnold
