Your test.py is to be interpreted as UTF-8 source code, according to https://docs.python.org/3.12/reference/lexical_analysis.html#encoding-declarations "If no encoding declaration is found, the default encoding is UTF-8.".

The escape sequence \xA0 is, according to https://docs.python.org/3.12/reference/lexical_analysis.html#escape-sequences "In a bytes literal, ... escapes denote the byte with the given value. In a string literal, these escapes denote a Unicode character with the given value.", meant to denote U+00A0.

You're right, it's a bug in xgettext.

To reproduce this bug, create a file "test.py" with the following content:


Then, run xgettext:

> xgettext test.py
xgettext: String at test.py:1 is not UTF-8 encoded.
          Please specify the source encoding through --from-code.

Adding 'u' prefix to string, fixes this issue. But it should not be the case for Python 3, as it treats string as Unicode by default.

(And adding --from-code does not work, because Python is exception from this option)

There is related old bug in Django, related to templates:


They're adding this prefix when converting {% trans ... %} tags to a code that gettext can understand. But this is workaround, and not a real solution.

Real solution should be on the gettext side, treating python string as "utf-8" by default (python 2 reached EOL long time ago). Or at least, adding an option for this.
