No, fix vim instead.

"Meta sets 8th bit" is so obviously and totally broken, since it maps 
onto real characters, and has been doing so for at least 20 years. 
Meta-L maps onto LATIN CAPITAL LETTER I WITH GRAVE, both in 8-bit mode 
and in your proposed UTF-8 mode.  It just becomes even more obvious how 
unbelievably broken it is when you try to map it onto UTF-8.

Seriously, fix the crap.
