virtualenv: Xonsh activation literals depend on the script decoding codec

Summary Caller-supplied prompt text can become executable syntax in the xonsh activation script. An attacker must influence the value passed to virtualenv, and a user must subsequently activate the environment. Affected area Xonsh reads a UTF-8 activation script using a legacy multibyte encoding...
