Because there are many lang_COUNTRY.UTF-8 locales:
ja_JP.UTF-8, zh_TW.UTF-8, fr_FR.UTF-8, etc...

If only en_US.UTF-8 should use surrogateescape, it may make confusing situation
like: "This script works in English Linux desktop, but doesn't work in
Japanese Linux
desktop!"

I accepted PEP 540.  So even if failed to coerce locale, it is better
than Python 3.6.
