Simplify a bit the special rules generating unaccent.rules
As noted by Thomas Munro, CLDR 36 has added SOUND RECORDING COPYRIGHT
(U+2117), and we use CLDR 41, so this can be removed from the set of
special cases.
The set of regression tests is expanded for degree signs, which are two
of the special cases, and a fancy case with U+210C in Latin-ASCII.xml
that we have discovered about when diving into what could be done for
Cyrillic characters (this last part is material for a future patch, not
tackled yet).
While on it, some of the assertions of generate_unaccent_rules.py are
expanded to report the codepoint on which a failure is found, something
useful for debugging.
Extracted from a larger patch by the same author.
