"Being on Ubuntu" tells a much less relevant story as

locale

does.  My own is comparatively weird with

LANG=en_US.UTF-8
LANGUAGE=en
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=POSIX
LC_TIME=de_DE.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=de_DE.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_ALL=

and has few localisation problems.  Other settings, however, may exhibit
more problems under some circumstances.  Particularly non-US settings of
LC_NUMERIC can mess up number formatting (like when generating
PostScript) and localised settings of LC_CTYPE are what tends to mess
with file name recognition and other console communication.
