groff_char(7) states, "a no-break space... is mapped to \~, the adjustable
non-breaking space escape sequence."
But as Deri and Bjarni point out in bug #62300, some fonts (including many URW
fonts groff installs for devpdf) include a u00A0 glyph, which is necessarily
of a fixed width.
Demonstration (when using -Tpdf):
.ft U-TR
a b c
.brp
a b\~c
.brp
a b\[u00A0]c
.brp
The results are the same if "\[u00A0]" is replaced with the corresponding
Latin-1 character.
