Re: ANN: Dogelog Player 1.1.3 (Tuning Trilogy)

My thoughts and prayers to Prolog systems that
have under the hood UTF-8. This is a nasty test case
to a certain approach of surrogate pairs:

?- X = 'The \uD83D', Y = '\uDE02 dog', atom_concat(X, Y, Z).
X = 'The \ud83d', Y = '\ude02 dog', Z = 'The 😂 dog'.

Could mean 3 bytes UTF-8 at the end of the first Prolog
atom and 3 bytes UTF-8 at the start of the second Prolog
atom are converted into 4 bytes UTF-8.
