Okay, Looks like the verdict is reached.

1.  "utf8" will stay liberal
2.  "UTF-8" will be strict

The rest is mostly implemenation.

2.1.  What will the canonnical name of the strict version of "UTF-8" be 
? Gisle already submitted me a test patch and it uses 'utf-8-strict'.  
If there is no objection, I would like to use that.

2.2.  CAVEAT: "UTF8" will be "utf8", not "utf-8-strict", since Encode 
aliasing is case insensitive.

2.3.  Degree of stricture. How strict are we going to make utf-8-strict?
    a. simply make use of UTF8_ALLOW_* in utf8.h ?
    b. unmapped codepoints banned as well?
    IMHO a. is strict enough since mapped codepoints are subject to 
increase
    as Unicode Standard updates.

2.4   We can always make "UTF-8" liberal by reapplying alias.

Anything else missing?
