This seems to relate to this issue, which has no assignee:

http://jira.codehaus.org/browse/JRUBY-6120

I should note this is in JRuby 1.6.5, and that removing the UTF-8 chars or the ERB code seems to bypass the issue.

I also got this bug, when I Set JRuby to run in 1.9 mode

@tom_enebo (on Twitter) fixed this for ERB renderer, but Erubis is still a problem. This breaks Rails 3 on 1.9, so it seems like it ought to be widespread for 1.9 mode. He says he's looking into this and should have a fix to test in the next week or so.

Tom says he hasn't had time to look into this issue, but should soon. I'll post again if and when I hear this issue is ready for some testing.
