Overall this looks good. I'll review / test it in detail later.

Quick comments on the PR:

1. You need to update the version number in .../legal/icu_web.md
2. Related to the above, can you create a new UPDATING.txt file in .../native/Source/ThirdParty/icu with instructions as to what needs to be updated when updating to a new ICU version, specifically including the changes to build.gradle, .../legal/icu_web.md, and /native/Source/ThirdParty/icu/CMakeLists.txt regarding updating the version number, along with anything else that isn't obvious (although I think the rest is straight-forward)?
3. Will the changes in core WebKit code (e.g., TRUE --> true) cause merge conflicts in the future?

Also, since this also addresses JDK-8232379, can you add it to this PR with /issue add 8232379?

I did a review of all change not in the ThirdParty/icu. All looks good to me. There is one more instance of the hard-coded 68.2 that could be defined as a property.

I've done sanity testing on Windows and and Mac. No problems that I can see. I'll do a bit more testing.

[kevinrushforth]

Testing looks good (all platforms). So do the changes.
