angular-translate sanitisation fails with UTF characters

At the moment, you have two options:

1. Use the strategy sanitizeParameters which will only sanitize the dynamic parameters, but not the actual translation (template). If you have the translation under control (but not the dynamic values), this will work.
2. Use the strategy escape (or escapeParameters) which does not use sanitization but escaping.

Disclaimer: I'm co-maintaining angular-translate.

Edit (12.01.2016): I'd created this matrix overview of all variants.
