MRI seems to always use UTF-8 by default when loading source files. This is used by the lexer & parser, but doesn't update the runtime's encoding. JRuby, on the other hand, seems to always use whatever the default_external encoding is, which is influenced by the system's locale.

$ cat enc.rb
p Encoding.default_external
p __ENCODING__

$ LC_ALL=C bin/jruby -v enc.rb
