XeTeX ⇒ Line breaks after dashes

[jpeyton]

I use XeLaTeX, and so I type in my quotes and dashes directly (i.e. I type “ and ”, not `` and '', and I type —, not ---). As I understand it, Unicode input is the proper way to do things, and it makes the source code cleaner.

However, my dashes will not break at the end of a line, meaning I need to use [draft] and manually add the line breaks.

Instead I’d like a line break to be possible either before or after the dash. However, sometimes dashes end a sentence, for example in dialogue:

Code: Select all

“Really? I don’t—”

In this case I would not want a line break either before or after the dash.

Any ideas?
