[Bug]: Infinite loop on bad $LANG #2178
Description
This was originally report to jest, but it appears the issue is related to yargs. I've copied the text and adapted a bit from the original ticket.
Version
Jest: 26.0.24, 28.0.3
yargs: 16.0.4
Steps to reproduce
$ LANG=.UTF-8 npx jest --help
RangeError: Maximum call stack size exceeded

Expected behavior
I expect jest to either warn, raise a proper error, or just continue if $LANG is bad.
Actual behavior
It appears to enter an infinite loop that blows the stack
