I recently updated pyuca[1], my pure Python implementation of the Unicode Collation Algorithm to work with 8.0.0, 9.0.0, and 10.0.0 but to get all the tests to work, I had to special case the implicit weight base for U+2CEA2. The spec seems to suggest the base should be FB80 but I had to override just that code point to have a base of FBC0 for the tests to pass.
Is this a known issue with the spec or something I've missed? James [1] https://github.com/jtauber/pyuca
