When trying to access the Hub, I just get a blank screen. It seems all.js throws a 500. If I request it directly, I get the following error message:

{"error":"U+00C2 from UTF-8 to US-ASCII"}

Any thoughts on what could be causing this?

Interesting, what OS version and Ruby version are you running?

Also could you stop the server minicron server stop and start it again using minicron server start --debug --trace and see if you get a stack trace?

Aha! The problem seems to occur only when starting minicron via Upstart. I suspect there's some environment variables set up in shell that aren't exported when running via Upstart.

Oh weird, could you still send over that info if possible so I can reproduce and make sure it's definitely not a bug?

Yup. Just needed to figure out how to recover the logs. Here's the relevant piece.

Changing the start command to the following solved it for me. Although it seems like assetpack shouldn't depend on whatever locale happens to be set.

LANG=en_US.UTF-8 minicron server start

Ha, I literally just found this rstacruz/sinatra-assetpack#76 (comment) which says exactly the same thing. It doesn't look like assetpack is going to fix it any time soon so I may just force Encoding.default_external to be UTF-8 on the minicron side. Thanks for reporting this 👍

Yes, I noticed that as well. Seems like forcing the encoding would be safe for minicron. Thanks!
