UnicodeEncodeError: 'ascii' codec can't encode character u'\\xe8' in position 15

I'm getting this traceback in my Apache logs every now and then:

0.10dev after the unicode branch has been merged? (i.e. ≥ r3024)

If not, can you try to upgrade?

[Alec Thomas]

Yep, pretty sure it was after the unicode merge. I did another update this afternoon, will update the ticket if I see it again.

[Alec Thomas]

I'd have a look myself, but I know exactly zip about character encoding and don't have the time to learn it at the moment :(

Cleaning up the traceback…

[Christopher Lenz]

This is about requests for the plain text view of wiki pages. Trac tries to write unicode data to the response, which then gets encoded to ASCII (instead of UTF-8).

Probably similar problems elsewhere where we use req.write().

[Christopher Lenz]

Fixed in [3029].
