By the way is that what the poster employed?
Also I just found this attested by Tolkien himself in 1948 [Christmas]: in letter 118 to Hugh Brogan Tolkien used quesse (number 4 in the chart in
The Return of the King) with the 's hook' when writing the word 'explanations' there -- with sort of a 'leftward' s-hook beneath quesse.
That's my e
ksplanation anyway
