Latex error ”Unable to read environment locale:exit now”
Emacs 25.3 with YateX outputs the error saying "Unable to read environment locale:exit now".
The following has fixed the problem:
'M-X setenv' and change 'LANG' into 'en_US.UTF-8', where "M-X" means pushing "Esc" key and "x" key.

「Unable to read environment locale:exit now」というエラーをEmacs with YaTeXが出力したので,'M-X setenv' をして,'LANG'を'en_US.UTF-8'に変更したら治った.ここで"M-X"は"Esc"キーと"x"キーの押下げ.
