Original GitHub issue: https://github.com/asciinema/asciinema/issues/103

When I try to run asciinema rec I will get the following error

asciinema needs a UTF-8 native locale to run. Check the output of `locale` command.

Output of locale command by default is

LANG=
LC_COLLATE="C"
LC_CTYPE="UTF-8"
LC_MESSAGES="C"
LC_MONETARY="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_ALL=

I tried to modify my locale settings as following:

LANG="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_CTYPE="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=

But it did not help.

What part should I modify in order to get asciinema run properly?

UPDATE: Tried to install from Homebrew, and version 0.9.9 worked correctly, but after upgrading it to version 1.0.0 I got the error back

It's about LC_CTYPE. asciinema expects it to be in format xx_XX.UTF-8 like others. It may be wrong assumption though, I'm now trying to find information whether "UTF-8" is correct value.

How can I update these variable without hacking with the environment variables?

I use ubuntu 14.04 & tried running

sudo dpkg-reconfigure locales
sudo update-locale LC_ALL=en_IN.UTF-8 LANG=en_IN.UTF-8

update-locale seems to update /etc/default/locale, but not the environment variables LC__/LANG_ variables

@thekalinga You can run LC_ALL=en_IN.UTF-8 asciinema rec.

Just go to Terminal > Preferences > Profiles > Advanced

Set: Text encoding to: Unicode (UTF-8)
Check: Set locale environment variables on startup.
