When trying to save this message, Emacs says:

These default coding systems were tried to encode text
in the buffer `copyright-sign-displayed-as-number.txt':
  (utf-8-emacs-unix (261 . 4194217)) (utf-8-unix (261 . 4194217))
However, each of them encountered characters it couldn't encode:
  utf-8-emacs-unix cannot encode these:
  utf-8-unix cannot encode these:

Click on a character (or switch to this window by `C-x o'
and select the characters by RET) to jump to the place it appears,
where `C-u C-x =' will give information about it.

Select one of the safe coding systems listed below,
or cancel the writing with C-g and edit the buffer
   to remove or modify the problematic characters,
or specify any other coding system (and risk losing
   the problematic characters).

yes, but made another mistake: this form needs a Python3, while reported when Python2 was used.

Please close, sorry,
