General ⇒ Hyphen replaced in ToC Entries

[nvx]

Has anyone here ever encountered

Code: Select all

\unhbox \voidb@x \kern \z@ \char `\discretionary {-}{}{}

being put into a .toc file instead of a hyphen? This causes the respective ToC entry to be typeset with a zero instead of a hyphen. Frankly, I cannot understand why this is happening, because other (sub)section headers containing hyphens are typeset as they should...


Thanks for any advice,

If your hyphen is a fragile macro, use \protect when you write it to the .toc file.

Then you should post a minimal working example that shows the problem (only if Stefan's proposal doesn't help you). How do you insert the hyphen?

Dear Stefan,

thanks for such a prompt response. I had no idea that there is something called 'fragile macro' or that a hyphen can be a macro by itself. Nevertheless, placing \protect before the hyphen worked like a charm.

How do you insert the hyphen?

Stefan's suggestion was dead-on, but thanks anyway. As for the hyphen, I inserted it in the regular manner: a single hyphen character (dash) - no double- or triple-dashes or special characters (en-dash, em-dash, ...).

Hmm... seems that some package or the class you're using is making - an active character and defined it in a fragile way.
