Most languages that already have some support for Unicode have a
significant amount of legacy code to continue supporting, though. Python
has the same problem: there're still heaps of Python 2 deployments out
there, and more being installed every day, none of which do Unicode
right.

To fix Unicode support in Python, the developers and community had to
initiate – and is still working through – a long, high-effort transition
across a backward-incompatible change in order to get the community to
Python 3, which finally does Unicode right.

Other language communities will likely have to do a similar huge effort,
or forever live with nearly-right-but-fundamentally-broken Unicode
support.

See, for example, the enormous number of ECMAScript deployments in every
user-facing browser, all with the false assumption (§2 of ECMA-262
<URL:http://www.ecma-international.org/publications/standards/Ecma-262.htm>)
that UTF-16 and Unicode are the same thing and nothing outside the BMP
exists.

And ECMAScript is near the front of the programming language pack in
terms of Unicode support — most others have far more heinous flaws that
need to be fixed by breaking backward compatibility. I wish their
communities luck.
