When i attempt to add a file with russian symbols in name to the model instance through default instance.file_field.save method, i get an UnicodeDecodeError (ascii decoding error, not in range (128) from the storage backend (stacktrace ended on os.exist). If i write this file through default python file open/write all goes right. All filenames in utf-8. I get this error only on testing Gentoo, on my Ubuntu workstation all works fine.

class Article(models.Model):
    file = models.FileField(null=True, blank=True, max_length = 300,
                            upload_to='articles_files/%Y/%m/%d/')

Traceback:
