[bug #63074] develop convention for encoding Unicode character sequences for passage to output drivers

[G. Branden Robinson]

Update of bug#63074 (group groff):

                Category:                    Core => General                
                 Summary: [troff] support construction of arbitrary byte
sequences in device control commands => develop convention for encoding
Unicode character sequences for passage to output drivers

Follow-up Comment #30:

Deri's right that his `stringhex` solution, and the underlying problem it
solves, aren't fundamentally about how the formatter talks to the device
driver (though that is ultimately a necessary step), but how macro packages
can sensibly pass Unicode character sequences internally and among each other
without trying, and failing, to pun between *roff string contents and *roff
identifiers, a bit of code jockeying that worked fine back in the days when
everything was ASCII (or at least ISO 8859).

Re-categorizing to "general" and updating Summary.
