support for Unicode 12.1.0

[stevengj]

Via utf8proc 2.4.

This adds exactly one character: U+32FF SQUARE ERA NAME REIWA.

Travis OSX failure is unrelated failed running test FileWatching.

I'll merge in a day or so if there are no objections.

[PallHaraldsson]

Should we backport this to Julia 1.1.1 (too late?) and/or 1.2? As a possible PR stunt to get the Japanese [emperor] exited for Julia?

[StefanKarpinski]

No, this is a feature.

[PallHaraldsson]

Ok, understand for 1.1.1. But not to late for 1.2 as its not released and this a trivial change.

[StefanKarpinski]

Every change has risk. What's the upside? One extra character? It's up to @KristofferC.

[KristofferC]

I think SQUARE ERA NAME REIWA has gotten too much time dedicated to it already ;)

[JeffBezanson]

We have a process. We don't just keep adding anything we feel like to a release up until the moment it is final. That wouldn't work. We declare a feature freeze, and after that point we only add important bug fixes and fixes needed to maintain compatibility. Otherwise a release would never converge to something stable, and we'd have to spend time debating each extra change somebody wants to add, like we're doing now.

I sent PR to utf8proc to make Julia support 'U+32FF'.
But I don't need the new character so far as my Julia programming, I'm only interested in technical feature.
I don't need that feature in the next release of Julia immediately. If necessary, I use development build of Julia at my own risk.
