Looks like it's language specific. It works with languages en,fi,ms,it. With de, the copyright symbol isn't announced but the year is.
I'm guessing it has something to do with the language change (^ in fr_list):
espeak-ng "recorder 2020" -v fr -x (en)rI2k'o@d3(fr) dY mil v'E~
espeak-ng "© 2020" -v fr -x sE~b'Ol(base) @@@ @@@ @@@
Note the language doesn't seem to change correctly in the latter example.
Also, the copyright symbol is defined differently in fr_list and fr_emoji. Could that affect it? Which one is correct?
