Bram,
:h expr-string states
,----
| \u.... character specified with up to 4 hex numbers, stored according
| to the current value of 'encoding' (e.g., "\u02a4")
| \U.... same as \u....
`----
However when using i_Ctrl-V_digit, one can use 'U' for up to 8
characters and using \%U also takes up to 8 digits.
So I think, it makes sense to have \U in a quoted string also accept up
to 8 characters.
So here is a patch.
Best,
Christian
