But turning an input method on and off is just 1 key, C-\, whereas
C-x 8 is 2 keys, and not very convenient sequence to type, at least on
QWERTY keyboards.  So it looks like a dedicated input method will
still be a win.  I don't think it's right that the only Unicode input
method we have is TeX -- that is great for TeX users, but many people
don't use (La)TeX, and will find it unintuitive to type the TeX
sequences.
