Neovim: Neovim trips on UTF-8 characters

[janko]

I installed the latest master of Neovim. However, I have some UTF-8 characters in my .vimrc, and also when I open a file with UTF-8 characters, Neovim throws an error for each UTF-8 character it finds (each error message is different, because they appear in different contexts, so I can't pull out a specific one). I have a :set encoding=utf-8 in my .vimrc, and Neovim was working fine before, there was just some change meanwhile that trips it up now.

:set encoding=utf-8

That's default, so shouldn't be needed (unless your locale set by $LANG isn't UTF-8). I triggered the following error by setting $LANG to en_US.ISO-8859-1 and launching nvim:

Error detected while processing function gitgutter#highlight#define_signs..gitgutter#highlight#define_sign_text:
line    4:
E239: Invalid sign text: @�
Press ENTER or type command to continue

Are your error messages similar to that? And can you verify that encoding is indeed being set to utf-8 by running :set encoding in a UTF-8 encoded file?

[janko]

Yes, I'm also using vim-gitgutter, and one of the errors is exactly this one.

It seems the following lines somehow dissapeared from my .bash_profile, and when I add them back, Neovim works properly:

export LC_ALL=en_US.UTF-8  
export LANG=en_US.UTF-8

Neovim worked before with UTF-8 without these settings, but that was probably an unintended "feature", which got rightfully removed.

@janko-m .bash_profile is actually not a good place for these settings. I have $LANG ($LC_ALL is not defined) in /etc/env.d/99locale (AFAIR file was created when system was installed) which specifies data for automatically generated /etc/profile.env which is sourced by /etc/profile. Pretty sure your distribution has something like this to specify $LANG system-wide. And I think without this setting system-wide if your locale was any but English you would not get correct locale in GUI applications.
