Throw 'ascii' codec can't encode character '\xe9' when inviting someone to a project

[NokiDev]

Do you want to request a feature or report a bug?

A Bug

What is the current behavior?

Throwing

If the current behavior is a bug, please provide the steps to reproduce.

Get a user from an LDAP server with an accentuated char in it's cn (Full Name) and try to invite him to a project trough an email

Note : my LC_TYPE is set to fr_FR.UTF-8 and TAIGA_DEFAULT_LOCALE set to fr

If that matter I'm using https://github.com/riotkit-org/docker-taiga setups scripts

What is the expected behavior?

Not throwing

Is it happening in taiga.io or in your own instance?

My own

What browser/version are you using?

N/A but Firefox 70.0.1

Are there any console errors (Ctrl + F12) in red?

UnicodeEncodeError: 'ascii' codec can't encode character '\xe9' in position 474: ordinal not in range(128)

[eldios]

taiga-back version 5.0.10 here and getting a suspiciously similar error:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 11143-11145: ordinal not in range(128)

I'm not using any accent just a simple plain email... was using with "italian" localization, reverted to "en" but still no luck.

Thanks.

Edit: here's the full error, which was generated while trying to add new users to a new project. Taiga is freshly installed so can do any test:

[eldios]

found the error... had to add the env variable:

PYTHONIOENCODING=utf8

and everything worked again
