If I want the output 𐐀g, I can create a map like this:

imap <F2> <C-V>U10400g

However for output 𐐀f, it causes a problem:

imap <F2> <C-V>U10400f

as the f is confused as part of the character. I can work around by adding leading zeros:

imap <F2> <C-V>U00010400f

but I would prefer a terminating key if possible. I came up with this:

imap <F2> <C-V>U10400<CR>f

but it puts a newline between the two characters. Is it possible to do what I am trying to do?

The documentation explicitly recommends using the maximum number of digits. See :help i_CTRL-V_digit:

Normally you would type the maximum number of characters. Thus to enter a space (value 32) you would type <C-V>032. You can omit the leading zero, in which case the character typed after the number must be a non-digit. This happens for the other modes as well: As soon as you type a character that is invalid for the mode, the value before it will be used and the "invalid" character is dealt with in the normal way.

I have found, however, that a command such as CTRL-], which triggers abbreviation, without inserting a character, is enough to break the sequence, without an undesirable side effect.

This seems to work fine:

inoremap <F2> <C-V>U10400<C-]>f

But I'd still recommend the solution using the three leading zeroes, as it's less "hacky" and it's the one recommended in the documentation.
