Description
Hi, there's known problem on Windows with parsing dotenv files - pypa/pipenv#1963. python-dotenv would parse files with default encoding (cp1251 for Cyrillic Windows). As a result we get Лист 1 instead of Лист 1.
It looks like this function need to fetch encoding from Config class somehow.
Example
.env file (UTF-8):
foo=Лист 1
Code snippet:
import pydantic
class Settings(pydantic.BaseSettings):
foo: str
class Config:
env_file_encoding = 'utf-8'
settings = Settings(_env_file='.env')
print(settings)
# foo='Лист 1'
