\xe9 is "é" in latin1, it may be the last letter of my name. no clue how it got there. suspecting this is related to the fix in proxy.py utf8 troubles, since this was not happening before the upgrade from squeeze. --anarcat

Ooops... turns out the plugin was enabled, through the rst plugin. After disabling it, the crash is gone, but one page isn't rendered anymore:

removing art/histoireinternet/index.html, no longer built by art/histoireinternet.rst

Here is that source file: http://anarc.at/art/histoireinternet.rst - and it seems encoded properly:

$ curl -s http://anarc.at/art/histoireinternet.rst | iconv -f utf8 -t latin1 | iconv -f latin1 -t utf8 > /dev/null

So I am not sure what is going on here... --anarcat

Python is decoding what it receives from IkiWiki using the default ascii codec. To match IkiWiki's "all source text is UTF-8" assumption, the Python proxy should explicitly decode incoming text from bytes (str) to unicode using the utf8 codec instead.

Python's conservative default is "ascii, regardless of locale" - this minimizes the chance of silently incorrect decoding, but unfortunately also maximizes the chance of crashing. --smcv

Right, I know that. The trick is to find the rabbit hole. :P

And I found it. With my dev/proxy-utf8-fail, this doesn't fail anymore. Yay, a patch ready for commit! --anarcat

I don't see that branch in your git repo, could you repost it please? (I'm trying to review some of the pending patches.) --smcv

Ooops.. I forgot to push the branch, it should be good now! --anarcat
