I have a document that has word-initial dashes (they indicate that the "word" is
a suffix). When the paragraph they're in is just right, xelatex insists on
inserting an unwanted line break immediately after the dash. I've tried lots of
things to prevent this: setting the lccode for dash to zero, replacing the ASCII
dash with an en-dash (U+2013), using or not using a {} immediately after the
dash, putting an \mbox around the dash and word (works, but difficult to use in
the particular context I'm working in), and several other things that I can't
remember right now.
Another thing I've tried is to set the \exhyphenpenalty to 10000. This works if
I do it in the preamble, but I don't really want it to have scope over the
entire document. But if I put that command inside a {...} together with the
dash+word, it has no effect.
Using a Unicode non-breaking hyphen (U+2011) appears to prevent the line break
when I try this with a different font. Unfortunately, the font I need to use
doesn't have a glyph for this code point, so I get a box in the PDF. (Is there
a way to use the ASCII dash glyph for this code point, while preserving the
non-breaking status of the U+2011 code point? Short of hacking the font.)
My MWE is after my sig line; the unwanted line break appears between the dash
and the "abcd". This behavior seems to be exquisitely sensitive to things
around it, including the remainder of the paragraph, and the presence of other
dashes within the paragraph; hence the text may seem longer than it needs to be,
but I couldn't get the same bad result if I shortened it much.
Suggestions?
