poetry install: `--no-ansi` uses non-ascii character ( `•` - `\u2022` - `BULLET`)

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Ubuntu 16.04 on Docker

• Poetry version: 1.1.0

• Link of a Gist with the contents of your pyproject.toml file: Unable to expose due to company’s security policy

I got an this message from docker

then I ran same command on macbook (iTerm2) and I could see a BULLET(\u2022) character. I searched about BULLET character on google and it is not an ascii character.

Printing non ascii character BULLET in --no-ansi mode seems to be fixed.

This is not really a poetry specific issue. And we use non ascii characters elsewhere too.

The issue here is the Ubuntu container. Additionally, this is a non issue for python 3.7.

@abn Thanks for letting me know! after I fixed container locale, poetry install succeed.

But as you know, most people don’t specify locale in Dockerfile. Using BULLET is likely to cause problems for many people using poetry on docker(or any ascii only environment), so I suggest going back to dash symbol as it used to be.
