tr: Illegal byte sequence

In my macOS Sierra bash terminal, the command below doesn't work:

$ export S3_BUCKET=example-state-store-$(cat /dev/random | LC_CTYPE=C tr -dc "[:alpha:]" | tr '[:upper:]' '[:lower:]' | head -c 32)
tr: Illegal byte sequence

Because of that, my $S3_BUCKET is not good.

$ echo $S3_BUCKET
example-state-store-

@wombat can you take a look at this? can you talk to @riywo to clarify this?

The command works on my machine.

Worked with LC_ALL=C instead of LC_CTYPE=C. cf. comment section of https://coderwall.com/p/4zux3a/random-string-generator-bash

$ cat /dev/random | LC_ALL=C tr -dc "[:alpha:]" | tr '[:upper:]' '[:lower:]' | head -c 32

Because I'm using Bash v4.4.12:

$ echo $BASH_VERSION
4.4.12(1)-release

@riywo I also use bash 4.4.12(1)-release and both versions work for me

Hmm. My locale is like below in my bash:

$ 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"
