Error when using a UTF8-encoded filename

[metakermit]

Using a filename encoded as utf8 (i.e. a normal Python3 string) results in an error:

This is how I'm using the storage (works when I use an ASCII string):

from io import BytesIO
...
self.barcode.save(
    "Maja Majić",
    BytesIO(response.content),
    save=True
)

Hi , what do you recommend ? can you make a PR ?

[metakermit]

I'm not sure how to fix this straight away, unfortunately. I made a workaround to always use ASCII chars in the filename (e.g. just use the object id) to avoid this error.

[royendgel]

Ok , I will make something in this days.
