Thanks.

Okay.  Of course it also depends on the platform, the tools,
what the user intends to do (read or edit), and what's more
user friendly in the case of unsupported characters.  

Admittedly my preferences are odd (= "all I need to know is
the hex. codepoint number for anything above u+00FF"), and
arguably RFC 5198 says "not good enough, hex. is not NFC".

The three servers I use at the moment are not "my" servers.
One of the them happily says Latin-1 for any text/html, no
matter what it really is.  As it happens it is either ASCII
or windows-1252, never Latin-1.  I don't see that the HTTP
or HTML5 WGs intend to improve this situation, putting it
mildly.  The concept "your server" is already broken, it's
the same idea as "your UA".

Right, I was curious if 10% was based on some reproducible
results for the languages allegedly covered by Latin-1.

Not fair, UTF-7 was an important step in 1994, at that time
UTF-8 was apparently still "work in progress".  An IETF AD
volunteered to sponsor an Internet draft deprecating UTF-7,
maybe try it.  My attempt failed, I ended up with talking
about UTF-32, UTF-16, UTF-8, CESU-8, UTF-1, BOCU-1, "UTF-4",
UTF-EBCDIC, UNICODE-1.1, and "UTF-5" - excluding SCSU isn't
the trick to get a remotely comprehensible text.
