"UCS2 is almost never found in the real world."
Windows 2000/XP/2003/Vista/2008/7 is almost never found in the real world?
Moving to Python 3

So, no, Windows isn't an example of UCS2, and hasn't been for many years.

In this sense, UCS-2 is extremely often found in the real world.

What were you imagining they should be using java.lang.String.codePointCount() for ? Text is hard, like I said, and a count of Unicode code points is rarely what you need.
Examples of things which are assigned one or more Unicode code points: A harmless, invisible and ignorable marker; indication that subsequent neutral text is intended to be displayed right-to-left; the cedilla accent on a character; a lowercase x; a vertical tab; indication that a non-fatal error occurred in some previous processing.

As the original poster said (even if their terminology is wrong in a bunch of places) UCS-2 looked like it might be clever in the mid-1990s. Once it became clear that Unicode's hyperspace would be populated, and UCS2 wasn't capable of handling that, the choice was no longer between UCS2 and UTF8 (where UCS2 delivers some intuitive-seeming properties, although not as many as sometimes claimed) but between UTF8 and UTF16, where UTF16 is completely horrible.
