Default character encoding for each operating system?

A better question is what is the default character encoding for the
**installed** operating system.

Unfortunately it has no single response, because there are several default
encodings for several parts of the OS. An OS has lots of components, many
of them don't are transparent to the encoding it uses.

All the 3 OSes you cite support several default character encodings, and in
addition they support them in several encoding forms. All three support
Unicode internally, but not in all software components. that will run with
one or the other.

And defaults will change according to your distribution or OS configuration
options, and to your own current user settings
