set_init_1: mb_init() on fallback encoding (utf8) #2106

Browse Source 
Explanation:
  Running `:set encoding=utf-8` _after_ startup correctly initializes
  multibyte; but mb_init() was _not_ called during startup if locale
  detection (enc_locale()) failed. This wasn't a problem in Vim because
  the Vim default encoding (latin1) does not require mb_init(). But Nvim
  defaults to utf8, so mb_init() is required.
