'' is falsey, and it causes the two functions to infinitely call each other

Addresses: #2178
Description
locale and kGuessLocale can enter an infinite loop
Details
There's regex logic that turns '.UTF-8' into '', and downstream there is logic checking if that value is falsey (instead of undefined).
As a result, kGuessLocale and locale call each other infinitely.
Todo
This line is what converts
'.UTF-8'into''. I don't know if my fix is sufficient or if the real problem is here.
