I hope this traceback from the serverlog on will help me to debug and fix this:

  • Status changed from new to needs_review

I have been unable to replicate the issue, even with rather exotic unicode characters (in the title and the body), but this should fix any possible problems (hopefully).

I think this should be closed. Codec related issues should be long gone, especially with the internationalization changes that have occurred since this.

  • Cc ppurka jason kini added
  • Milestone changed from sage-5.10 to sage-duplicate/invalid/wontfix
  • Status changed from needs_review to needs_info

If this is still valid, the relevant code has changed slightly, so this wouldn't apply. Also, we should probably create a pull request.

Or, as Tim suggests, if not, we could indeed close this. It's unfortunate William didn't attach a sample sws :( I'd go with Tim, though I think that we should have at least one current sagenb guru also confirm his statement.

Appears to be fixed in SageNB; see the upstream issue.
