Answer 1

That error message usually occurs when you try to concatenate strings with different character encodings.

Is your database set to use UTF-8 as well?

If not, you could have a problem when you try to insert the non-UTF8 values into your UTF-8 template.

Answer 2

The culprit that was leaking non UTF-8 characters in my template was an innocuous meta tag for Facebook Open Graph

%meta{property: "og:url", content: request.url}

And when the request is non-standard, this causes the encoding issue. Changing it to

%meta{property: "og:url", content: request.url.force_encoding('UTF-8')}

made the trick.
