Use of the collation algorithm to do this is probably overkill.
If you are looking to make arbitrary sets of equivalences, such
as "all the consonants of English", then you should probably just
write your own ad hoc foldings.

Don't expect to find such information out of a character encoding
standard or out of the Unicode Collation Algorithm.
The point of the character encoding standard is to encode all
the characters of each *script*, so that it can be used to
represent text in all the languages that use that script. The
character encoding standard, per se, doesn't do any language-specific
The point of the Unicode Collation Algorithm is to provide a
default sorting for Unicode, along with a generic tailoring
mechanism to allow people to customize it to produce
language-specific sorting according to cultural conventions.
Again, the algorithm, per se, doesn't do any language-specific

You need to start looking up *linguistic* sources for that kind
Unless what you are really after is just the list of characters
needed to represent text for each language. In that case, then
there are various online sources to get you started, as reported
several times on this list. For example, see Indrik Hein's site:

No, I don't think so.

ICU provides an implementation of the Unicode Collation Algorithm.
It conforms *to* UTS #10.
