I agree now that a new input method should be sufficient, and
no need to mess with 'C-x 8'.  All existing problems of input methods
will be solved in another request.  So here is a new input method:

Having a Multi_key-like input method makes sense to me.  I don't get
this bit, though:

`C-x \' doesn't seem to be bound in this Emacs, and your input method
doesn't bind it either?  There's probably something trivial here I'm
missing; I'm not really familiar with the Quail stuff.  Or did you mean
`C-x C-m C-\'?

Heh, never mind --

+(define-key ctl-x-map "\\" 'transient-input-method)

is in the next bug report.

I think "UTF-8" is not the best name for this.  How about "Unicode"?

This new method should be called out in NEWS.

Thanks.

This input method was based on the existing Unicode input methods
"TeX", "rfc1345", "sgml" that all use "UTF-8".  And `M-x list-input-methods'
puts all them under the "UTF-8" category.

Maybe something like this:

So here is the input method created from the 'C-x 8' keymap:
