Lesson 19 of the Instruction Manual for Braille Transcribing – UEB Edition, 2015 has a very informative section on special symbols and the special symbols page. I have found the explanation of "braille order" invaluable!
Just to confirm: we no longer need to list top and bottom box lines, copyright symbol, forward slash, crosshatch, bullet or the ampersand? I see that many of the general symbols and indicators in section 3 of Rules of UEB are not included in your list (such as the ampersand, asterisk, daggers, bullet, caret, copyright...) Are these just considered common enough now?
Would the note separation line be listed, or just the line mode indicators?
If the closing single quotation mark is listed, would the opening single quotation mark be listed as well?
