If you're on a Unix OS (Linux or Mac), you have access to magic . If on a Mac, you'll likely need to brew install libmagic . There's a Python library called filemagic for rolling it into your Python scripts.

import magic
mage = magic.Magic()
mage.id_buffer("adsfadsf←")

The last line will return 'UTF-8 Unicode text, with no line terminators'

You can also have it check files, which isn't based on the filename but rather the magic bytes at the start of the file:
