I did not manage to see any. I was prepared to keep the old code and use 
it when not running utf8 but it wasn't needed. Some other mods make a 
non-utf8 NT boost from 24000K (jumbo 1) to >27000K on my machine (while 
--utf8 speed is near 21000K).

I'm not aware of any format performing worse in Jumbo-5 but many formats 
has got significant boosts.
