Upgrade ICU to 59.1 and later to 60

Project Member Reported by yangguo@chromium.org, Apr 15 2017 
V8 is implementing RegExp unicode property class escapes, a new language feature currently at stage 3 of TC39, so fairly soon part of the JavaScript specification. V8's implementation is based on ICU. Test cases in Test262 are based on Unicode 9.0.0 data, and we currently still see a few failures.

We expect some of these failures to go away with an upgraded ICU. For details see https://bugs.chromium.org/p/v8/issues/detail?id=4743#c28

Please assign to the correct owner. Thanks!

Hmm... ICU 58.1 (released in October 2016) does have Unicode 9.0 data (released in June 2016).  

You mean Unicode 10.0? 

Anyway, ICU in Chrome/v8 will be updated to 59.1 before long.

I read  issue v8:4743  comment 28 and it's about Emoji properties. Emoji data is updated more frequently than Unicode release. The latest Emoji data version is 5.0 (finalized about a month ago) and is indeed incorporated to ICU 59.1 ( http://bugs.icu-project.org/trac/ticket/12900 ). 

Once ICU in Chrome/v8 is updated to 59.1, that will indeed be fixed.

Even after updating to ICU 59.1, there’s still this remaining problem (from  issue v8:4743  comment 28):

> This failure was expected since ICU currently doesn’t support `Emoji_Component`.

It would be nice to have an open issue to track the eventual update to ICU 60. Perhaps we could re-use this one for that?
