shellcheck: encountered an exception while trying to report an exception.

[kirxkirx]

shellcheck does not work with a non-standard locale:

kirx@eridan ~/current_work/vast $ shellcheck util/search_databases_with_vizquery.sh
shellcheck: encountered an exception while trying to report an exception.
One possible reason for this is that we failed while trying to encode an error message. Check that your locale is configured properly.
kirx@eridan ~/current_work/vast $ locale

This is a binary version of shellcheck installed from the Gentoo repository (package name dev-util/shellcheck-bin).

Here's what I wanted or expected to see:

The expected behaviour would be for shellcheck to produce the normal English-language (if the current locale is not supported) terminal output instead of a cryptic English-language error message about "an exception while trying to report an exception".
