get_innerHTML returns a Unicode string. There is no need to escape those
characters with character entities, they are just being represented
directly as Unicode codepoints. Now, whatever it is you are using to
view the content clearly does not support rendering those characters,
that's why you see question marks.

You can't. If you want that, you need to post-process the string and
replace all Unicode codepoints you deem "unsafe" with character
references.

This method gives you the data exactly as sent by the server, with no
processing at all. Among other things, this means that it is not
necessarily Unicode text - the server could send the content in some
legacy encoding.

None that I know of.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
