Comments 10 and 11 of bug #55154 point out that due to the way .tr and .char
and their ilk handle translations, there is no way to translate an input
character to a stretchable unbreakable space.
The use case presented there (of working around the now-fixed bug #62300 in
older preconvs) would not be helped by a fix to this bug, since this fix would
not be available in older groffs. But there are other reasons one might want
to translate an input character to \~.
As Bjarni points out in bug #65654, many common Unix text-display tools make
U+0020 and U+00A0 visually indistinguishable, so the user might choose to have
a different character represent U+00A0 and let groff translate it
appropriately. While this is a simple translation to preprocess before groff
sees the input, it's such a simple translation that groff ought to be able to
handle it itself.
