There are a few extra points to notice here:
- Different .mo files may have different encodings.
- The translation system is made in a way that the programmer should
not have to worry about the encoding used by the translators.
- The current scheme may introduce a wrong practice: forcing
translators to use some specific encoding to avoid breaking the
- We already have support for getting the "unicode" version of the
string. This is currently the right way to get the translation in
some specific encoding, since it uncouples the translation encoding
from the expected encoding.
- In cases where you'd get the "UnicodeError", you'd see a mangled
string which would be unreadable. To avoid the UnicodeError, we
may also return the original string in cases where the
UnicodeError is raised.

Yes, it changes the default encoding.

Thanks for your suggestion!
