-# Note on LANG: On the way thud -> warrior something started to set

-# idea:
+# Note on LANG: Since systemd 240 LANG="C.UTF-8" is set if no /etc/locale.conf
+# is found and mentions that 'This locale is supported by various
+# distributions' and 'upstream glibc is going to make it available too' [1].

 # * german Umlaute cannot be displayed anymore
 # * at least menulibre does not start anymore and complains with
 #   | File "/usr/lib/python3.7/site-packages/menulibre/MenulibreApplication.py", line 390, in configure_application_actions
 #   |    label=_('Add _Launcher<65><72><EFBFBD>'),
