Runtime error trying to execute UI tests (and possibly all other programs?) on Raspberry Pi 4 (Debian bookworm 12.2.0-14, GCC 12.2)

[kneelian]

While the tests build without error with make termox.ui.tests after building the library, the resulting binaries all throw with the following response:

$ ./fixed.ui.test
terminate called after throwing an instance of 'std::runtime_error'
  what():  initialize_terminal(): setlocale() failed.
Aborted

This is presumably a problem further up the code chain, since the UI tests themselves don't contain any code that should cause this to throw, but I haven't searched through the code enough to say where the issue lies.
