4caf8a6b14 Restore support for alternate character sets 
Needed by the execrable ncurses. Adds an extra branch in the hot path,
sigh. Thanks to branch prediction it doesnt have any measurable impact
on the benchmark, thankfully.

1db7ac5f6b Use our new shift by n functions to improve function to zero last N bytes 
Benchmark neutral but cleaner code using one less vector register and equal
number of operations.

b5edd9ad57 Dont precalculate mask in loop body 
No need since we dont shift. Avoids the extra mask instructions for the
not found case.

618aeec709 Finally got gnome-terminal to run on my system 
Apparently it needed some kind of GTK desktop portal or the other
🙄

Interesting that its numbers are basically the same as alacritty's. Lot
better than I remember, I guess the recent libvte performance work was
good.
