Subject: bug#27505: LC_CTYPE affects tutorial language
Date: Tue, 27 Jun 2017 23:48:41 +0900

Dear all,

as far as I know the environment variable LC_CTYPE applies to
classification and conversion of characters, and to multibyte and wide
characters. So setting it should not influence the interface language,
correct?

However, with the following locale:
LANG=en_US.UTF-8
LC_CTYPE=zh_CN.UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE=C
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I find that the emacs tutorial (C-h t) is displayed in Chinese.

Is this expected behavior or a bug? This may or may not be related to
bug#27312 where I reported that I can't activate fcitx even though env
is set up correctly.

(I.e. the following is the first line of the displayed tutorial:
