Sure. I doubt that shortening in __get_locale might be insufficient
since some code may want the full locale name even if there is no
locale data for it. I will dig into the code.
Another problem is the preference of shortened locales. Obviously, the
full locale itself has the highest priority and language-only locales
(e.g. en, de, etc.) do the lowest one. However, which is the preferred
locale, en_GB@...o or en_GB.UTF-8, when the code receives
en_GB.UTF-8@...o?
I am unsure whether someone actually uses such locale, but I think it
is necessary to discuss such corner cases.
