here you have a little more

"JavaScript engines are free to use UCS-2 or UTF-16 internally. Most
engines that I know of use UTF-16, but whatever choice they made, it’s just
an implementation detail that won’t affect the language’s characteristics.

The ECMAScript/JavaScript language itself, however, exposes characters
according to UCS-2, not UTF-16."

I actually have to eat my hat.

Javascript runs UCS-2 (16 bit encoding) according to standards but
most browsers JVM's also supports UTF-16 there is a 16 or 32 bit
encoding.

However UTF-8 is directly compatible with UTF-16 (doesn't need trans-
lation tables but can be computed) but UTF-8 is a slimmer format in most
cases since it has a 8, 16, 24 or 32 bit encoding where the 8 bit encoding
(x'00'-x'7F') is compatible with ASCII 7 bit (x'00'-x'7F').

yes, and my example is probably the best proof that javascript runs

By "proof", do you mean that the script was able to handle the value of
the
first input element? I don't know what language that is, but I would agree
that it makes a compelling case for your hypothesis about the JavaScript
"engine" using UTF-8.
