It’ll depend on how you’re using it (and if it’s the cause of your error - the ASCII-8BIT data may be from something else) but you can see what I did in these commits:
https://github.com/alphagov/e-petitions/commit/1f63d9e179ea95bde1922d6b14ea9405547a2418 https://github.com/alphagov/e-petitions/commit/dd5c6ca1e0b1ac829272f1529d481a4604c3d0fa
It’ll mean you’ll get weird characters sometimes but that’s better than the page blowing up.
Thanks @pixeltrix. Your examples and suggestions helped a lot.
I managed to do more hunting, and eventually discovered somewhere we used
request.url(some meta tag for facebook,og:url…).Somehow view traces aren’t the most specific, which makes tracing those kinds of bugs much harder. But at least I found it! Thanks again.
I’m having a similar issue to @manfe. The odd thing is that the error depends on the request itself.
We have a template with a few UTF-8 characters, e.g.
ä. It renders just fine most of the time, but some times fails, depending on the request params.i.e.
removing the UTF-8 characters from the template renders fine in both cases.
Tried various changes like adding
# encoding: UTF-8on the template, using.force_encoding('UTF-8')on the string and various other hacks, but nothing seems to resolve this.(ruby 2.2.2 / rails 4.2.5.2)
