brew.sh no picking up correct locale

[russel]

The brew.sh script appears to ignore the locale information (en_GB.UTF-8 in this case), and impose
en_US.UTF-8, which doesn't exist on my machines.

• Ran brew update and retried your prior step?

|> brew update
/home/users/russel/.linuxbrew/Homebrew/Library/Homebrew/brew.sh: line 4: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8): No such file or directory
Already up-to-date.

• Ran brew config and brew doctor and included their output with your issue?

I saw that there is some discussion about this in the mac repository: Homebrew/brew#3666

Does this patch help?

[russel]

It looks the identical problem, certainly. I am not sure the right procedure to test the change, is there some blurb somewhere explaining what to do for this?

It seems that even though locale charmap returns UTF-8 the bash expression [[ "$(locale charmap 2>/dev/null)" != "UTF-8" ]] returns true, which is very weird.

This is the issue someone will need to figure out before we can accept an upstream fix for this.

[russel]

@MikeMcQuaid I suspect it is because locale charmap returns "UTF-8\n" which is not equal to "UTF-8".

Hi, Russell. ENV_FILTERING resets the language first to C and then to en_US.UTF-8. The workaround for now is to set the environment variable

export HOMEBREW_NO_ENV_FILTERING=1

[sjackman]

@MikeMcQuaid ENV_FILTERING is resetting the language first to C with a default charmap of US-ASCII in bin/brew and then setting it to en_US.UTF-8 in Library/Homebrew/brew.sh. Are you interested in a patch to protect the environment variables LANG and LC_* from being cleared by ENV_FILTERING?

[MikeMcQuaid]

Are you interested in a patch to protect the environment variables LANG and LC_* from being cleared by ENV_FILTERING?

Let's add the minimal required to fix this bug i.e. either LANG or LC_ALL.

[sjackman]

@russel Please report…

env | egrep 'LANG|LC_'

[russel]

@sjackman

@ralic Same for you: can we see env | egrep 'LANG|LC_'

[sjackman]

For me:

❯❯❯ env | egrep 'LANG|LC_'
LANG=en_CA.UTF-8

[MikeMcQuaid]

Thinking about this more: I maybe LANG or LC_* should not be whitelisted but instead the en_US.UTF-8 should not be set if it does not exist.
