Encoding error when saving file

[HeuristicPerson]

Hi. I've created a script to edit id3 tags of downloaded podcast episodes and I'm having an encoding issue with one of them. My configuration is:

  Python 3.8.10
  eyed3 0.9.6

The minimal version of the code that fails is:

o_audiofile = eyed3.load(po_file.u_path)
[...I edit other tags with no problem...]
o_audiofile.tag.title = self.u_mod_title
o_audiofile.tag.save()

And I'm getting this error:

File "foo/bar/dev/pod_dl/libs/podcasts.py", line 438, in fix_tags
  o_audiofile.tag.save()
File "/usr/local/lib/python3.8/dist-packages/eyed3/id3/tag.py", line 914, in save
  self._saveV2Tag(version, encoding, max_padding)
File "/usr/local/lib/python3.8/dist-packages/eyed3/id3/tag.py", line 1119, in _saveV2Tag
  rewrite_required, tag_data, padding = self._render(version,
File "/usr/local/lib/python3.8/dist-packages/eyed3/id3/tag.py", line 1038, in _render
  raw_frame = f.render()
File "/usr/local/lib/python3.8/dist-packages/eyed3/id3/frames.py", line 303, in render
  self.text.encode(id3EncodingToString(self.encoding)))
UnicodeEncodeError: 'latin-1' codec can't encode character '\u2013' in position 21: ordinal not in range(256)

Below you can check the original title tag of the mp3 file and the new one I assign:

It looks like an encoding problem but I don't know how to fix it. I've tried passing the new title encoded in utf-8 and also changing eyed3 default encoding (eyed3._DEFAULT_ENCODING = 'utf-8') with no luck.

OK, my fault. The IDE (Pycharm) wasn't suggesting any parameter but I see at https://eyed3.readthedocs.io/en/latest/eyed3.id3.html?highlight=tag.save#eyed3.id3.tag.Tag.save that the encoding can be specified when saving the file which solves my issue:

BEFORE (not working):

o_audiofile.tag.save()

NOW (working):

o_audiofile.tag.save(encoding='utf-8')
