editor creates mal-formed .js files

[jrv]

start ebook-edit
file, create new empty book
epub
give name and save in convenient directory
file, newfile, functions.js, ok

expected: empty file functions.js opens
actual: file opens with text
  b''

replace text with
  function aFunction() {
    console.log( 'in aFunction' );
  }
save
close ebook-edit
open just-created .epub using ebook-edit
if not open at start, open functions.js in the editor pane by double clicking on file browser panel

expected: editor to open with contents
  function aFunction() {
    console.log( 'in aFunction' );
  }
actual: editor opens with contents
  b"function aFunction() {\n console.log( 'in aFunction' );\n}"

It looks to me as though python string literals are put in the editor rather than the eval of those python string literals
