Followed your instruction and compiled an emacs binary from the
scratch/gnus-decoded branch.

1. When listing Groups in the Group buffer using (l) or (L), all good.

2. In a group Summary Buffer, when moving (B m) an article to a new
   (non-existent) group in English, Gnus asks, creates group & moves article.

3. Same group Summary Buffer, moving to a Greek named  group, Gnus asks
   with name encoded as numbers and fails to create group. Here is
   '*Message*' buffer:

   : Generating summary...done
   : Loading quail/greek...done
   : No such group: Dias/£º…»¹ƒ¹±–‰·.  Create it? (y or n) y
   : gnus-read-move-group-name: Couldnt create group Dias/£º…»¹ƒ¹±–‰·
   : No more articles [2 times]
   : No such group: Dias/–‰·•½¤±†¿.  Create it? (y or n) y
   : gnus-read-move-group-name: Couldnt create group Dias/–‰·•½¤±†¿
   : next-line: End of buffer
   : No more articles [2 times]

Also, trying to save the above text in a separate file, I get (after
setting the coding system to utf-8-emacs-unix):

   : These default coding systems were tried to encode text
   : in the buffer emacs-gnus-group-2019-06-19.txt:
   :   (utf-8-emacs-unix (74 . 4194254) (75 . 4194211) (76 . 4194254) (77 . 4194234) (78
   :   . 4194255) (79 . 4194181) (80 . 4194254) (81 . 4194235) (82 . 4194254) (83 .
   :   4194233) (84 . 4194255))
   : However, each of them encountered characters it couldnt encode:
   :   utf-8-emacs-unix cannot encode these:           ...
   :
   : Click on a character (or switch to this window by M-x other-window
   : 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).
   :
   :   raw-text no-conversion


Hope this helps.
