I have the following \hbox
, and if I unbox it and put it to a paragraph (or when I just type aaa --, bbb
or aaa --\nobreak, bbb
), TeX is breaking the line between --
and ,
.
> \box0=
\hbox(6.88875+1.94443)x46.1109
.\T1/lmr/m/n/10 a
.\T1/lmr/m/n/10 a
.\T1/lmr/m/n/10 a
.\glue 3.33333 plus 1.66666 minus 1.11111
.\T1/lmr/m/n/10 ^^U (ligature --)
.\T1/lmr/m/n/10 ,
.\glue 3.33333 plus 1.66666 minus 1.11111
.\T1/lmr/m/n/10 b
.\T1/lmr/m/n/10 b
.\T1/lmr/m/n/10 b
My questions:
Why does such a line break happen?
Why doesn't
\nobreak
disable the line break?Is it possible to fix it so that no line break happens when the source file contains
--,
(without any wrappers like\hbox
or\mbox
)?

also apply to ligatures ending with that character--
