Always got "Please ensure your locale is set to UTF-8"

[jsvisa]

My locale is set as below:

LANG=
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=C

When I run iex, it always got

warning: the VM is running with native name encoding of latin1 which may cause Elixir to malfunction as it expects utf8. Please ensure your locale is set to UTF-8 (which can be verified by running "locale" in your shell)

I don't know how to avoid it.

You need to set those variables properly. Here is how it looks in my machine:

$ locale
LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_ALL="en_US.UTF-8"

See this Stack Overflow answer for more ideas. Finally, please use the mailing list or stack overflow for questions.

You need to set at least LANG and LC_CTYPE.

Thanks @josevalim , I'll check it now

You need to set those variables properly. Here is how it looks in my machine:
...
LC_ALL="en_US.UTF-8"

Just for the record. I don't think you should set LC_ALL in your config files, as it overrides everything. If you had set every other LC_ env variable, there is no need for LC_ALL, and actually they will be overriden.

Reference: https://wiki.debian.org/Locale

Warning! Using LC_ALL is strongly discouraged as it overrides everything. Please use it only when testing and never set it in a startup file.
