On the Windows platform if you select "Automatic" for language, it
won't actually select correctly for the Chinese languages. This is
because our Windows code returns a locale like ""zh_CN" or "zh_TW",
not the "zh_HANS" and "zh_HANT" expected. This PR checks for language
code "zh" and will then will append "_HANT" if your 2-letter region
is TW (Taiwan), HK (Hong Kong), or MO (Macau), and "_HANS" for other
regions (like China, Malaysia, Singapore, etc).
