Java/the JVM says hi!

Arguably, "how many bytes does this string occupy in memory/on disk (e.g. in class files)" is a pretty useful thing to be able to ask.

Sure. On disk those strings are (modified) UTF-8 of course, is that what you meant ?

On disk yes, at runtime it's still UTF-16, I believe.

This is still relevant for many databases as well, as far as I remember.
