mitmproxy should check LC_CTYPE before LANG when testing console environment

See original GitHub issue

When I run mitmproxy 0.9, I see:

% mitmproxy --version
mitmproxy 0.9
% mitmproxy
Error: mitmproxy requires a UTF console environment.
Set your LANG enviroment variable to something like en_US.UTF-8

But my console environment is UTF-8 already:

% locale
LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

When I check the locale(1) manpage, it says that LC_ALL, if set, overrides LC_*, and that LANG is just a fallback for unset LC_* values. But every possible LC_* value other than LC_ALL is set, so there is no need to set either LC_ALL or LANG.

@abit2: You need to change the process environment. This should work:

env LANG="C.UTF-8" mitmproxy
