[bug #58930] take baby steps toward Unicode

[Dave]

Follow-up Comment #27, bug #58930 (project groff):

Hmm, the fallbacks.tmac changes in the resolving commit are having an effect
on ASCII output I can't (yet) explain.

If I run a groff _without_ this commit:

$ echo 'I \[dg] you' | groff-latest -Tascii -mtty-char | cat -s
I <*> you


This is the expected output: tty-char.tmac defines \[dg] as output above.

But applying the commit 132182bd7 changes to fallbacks.tmac makes this go
awry:

$ echo 'I \[dg] you' | groff-latest -Tascii -mtty-char | cat -s
troff:<standard input>:1: warning: special character 'dg' not defined
I  you


I don't understand this, because while the updated fallbacks.tmac defines a
new character _as_ \[dg], it does (or should do) nothing to change the
definition of \[dg] itself.  The same is true of \[dd], which shows the same
effect.

This can be a new bug report if that makes more sense.
