[bug #64484] [troff] \X escape sequence should read its argument in (something like) copy mode

[Deri James]

Follow-up Comment #16, bug #64484 (group groff):

Hi Branden,

Thanks for this. I appreciate you explaining what you are trying to do. I
wonder if it would be possible for you to setup a branch on Savannah with your
code changes so we can both investigate for any problems. I'd love to see the
sboxes issue.

Running your for-deri.man example on current git I also get exactly the same
results, so I am not sure what effect your changes are making. If you add
"-fU-T" to the command you may see proper greek glyphs rather than slanted
stuff from the symbol font, it depends, not all URW fonts are the same, some
have proper greek glyphs, some don't. We ought to install the SS font for
devpdf, part of the deri-gropdf-ng branch.

I have a couple of one liners to illustrate current \X and .device behaviour,
which is why I get palpitations when you write (after talking about \X) that
"I've just about got the `device` request converted over to the same thing"!!
I realise you are talking about the "third way" (which could be a very good
thing) but it points to bug #63074 which in turn points to bug #65108 where
rule 5d restricts unicode to \[u00XX] 00-1f and 80-FF, a minute subset of
unicode.

printf  ".ft U-TR\n\X'ps: αβγabc'\nαβγabc"|test-groff -Tpdf -Kutf8 -Z

printf  ".ft U-TR\n.device ps: αβγabc\nαβγabc"|test-groff -Tpdf -Kutf8
-Z

Cheers 

Deri
