Start by reproducing the failure with `llk` or `logkeys --start --output test.log` under the reported Debian/Linux locale, and inspect the `locale` output provided in the issue. Determine why `LC_CTYPE=es_AR.UTF-8` is rejected; done means logkeys starts successfully and creates the expected output instead of stopping with the UTF-8 error.
