Review Comment:
Thank you for the feedback.
I adjusted the implementation and documentation. In the original commit, I
followed the implementation of `mime.extension`, which is set to an empty
string, when it cannot be determined. Should its implementation stay as is or
be changed as well, such that it does not be set like `mime.charset`?
