(short answer)  You are on your own.

(standard answer)  'perldoc perllocale', read it.  (It's hard to
understand, yes).

(bullshit answer)  How you run mysterious script and your operating
system are desynchronized.  I suspect, something resets environment for
mysterious script and/or child processes (because fsck you;  maybe
grounded in security or whatnot).  Then sneaks (or inherits, who knows)
$LANG.  That $LANG refers to locale that is missing from your system
(for whatever reasons).

Now, there are multiple goals to choose.  And, respectfully, multiple
approaches to the goal you choosed.  It's up for you to decide.

But foremost.  How locale and environment are handled and maintained
heavily depends on (and is specific to) your operating system.  No,
linux is just a kernel.  No, GNU/Linux doesn't say anything.  No,
Kubuntu (or whatever sister) isn't that widespread.

IOW, your problem (if any) has nothing to do with perl or Perl.  Please
disregard standard answer.

P.S.  gnuplot?  Insert here thatsnameihaventheardforlong.jpg
