is it really?  would an average Greek, Russian, Chinese, Japanese,
or Korean speaker really understand the mapping between characters 
and length of UTF-8 representation any better than the mapping 
between characters and length of (say) DUDE representation?

seems like if the limits are specified in any other form than 
"maximum number of symbols" then users will find this mysterious.
and for many languages UTF-8 requires different octet lengths for 
different characters.
