unicode-data-0.4.0.1's test cases seem to break with the newer GHCs. (newer base versions)
See: #118
I can confirm that this is the case for 9.10 and 9.8.
But the CIs for the latest master are passing so the problem seems to have been fixed.

The hackage has version-bounds for base that are incorrect. With base-4.20 above mentioned test fails

Can release a newer version of unicode-data with the fix included?
We can then, update the dependent packages accordingly.
Should we re-revise the version bounds on hackage?
