When I'm trying to commit a binary file into a repository and setting the encoding to "base64" (as specified inhttps://docs.gitlab.com/ce/api/repository_files.html#create-new-file-in-repository), I'm getting the following error:

Traceback (most recent call last):

return _iterencode(o, 0)

This makes it seem like the python api is ignoring the encoding option. I've ensured the encoding is set to base64 in the 'blob' that I've passed to project.files.create(). Other ordinary files without the encoding commit perfectly fine.
