In traditional typography, the em-rule is optional and can be replaced
by a (spaced) en-rule. In TeX, en-rules are represented by two hyphens (--) and the em-rule
by three (---). This is always approriate except in typeset documents
(i.e. PDFs produced by TeX). Either you typeset something or you don't. |
