Unicode characters are removed from .po when they are in msgstr

[JSteunou]

Describe the bug

When using po format and adding some unicode char like \xA0 in msgstr it works at runtime, but running the CLI to extract messages remove all of those char

To Reproduce

msgid "Welcome!"
msgstr "Bienvenue\xA0!"

Save it, extract again, boom, \xA0 is gone

Expected behavior

Should keep this char

Additional context
Add any other context about the problem here.

• jsLingui version lingui --version 3.10.4
• Babel version npm list @babel/core 7.14.6

I tried to play with jsesc configuration, all kind... no luck :(

We remove extra-scaped literals, probably we should add there. /x together with /u.

What do you think?

[JSteunou]

I m not sure, because my issue is not for char in the key or message extracted by the macro logic, but in po files msgstr section aka the final translation.

The issue here is that running the CLI to discover new translation keys corrupt the current dictionary which is kind of worse I guess?

[semoal]

Macro is the responsible of generating the final translation.

[JSteunou]

Ho ok I did not understand that. With that name I supposed it was only the part responsible for extraction from code (babel-macros / Macro). Also the tests from the commit you linked shows a test with extraction key, not value from dictionary.

Then yeah it might be linked, worth the shot
