Uh? If you call trUtf8(), it means that you are passing in a UTF-8 encoded
string. With UTF-8, you can represent any codepoint in the Unicode standard,
so there is no problem with that.
>From a *pratical* point of view, you just want to:
- Mark your Python files as UTF-8 (using the standard encoding declaration:
- Use a text editor which will actually edit contents in UTF-8 form (for
instance, a Python-aware editor that will automatically adapt to the
encoding declaration of the file; or a simple text editor like vim running
with UTF-8 locale).
- Always use trUtf8(), or use tr() after having called
and that's all.
