I'm not (yet :-) a VIM user but with most text editors (e.g. in Geany) you can input UTF-8 code points like this:
1) press together  the release [Ctrl]+[Shift]+u => displays an underlined u
2) Type the two hexadecimal digits of the code point
3) Press [Enter] (not always necessary, depends on the editor)

Example : <SI> is the ASCII command character Shift In, hexadecimal code 0F

ASCII being a subset of UTF-8 with the first digit set to 00, you can input it this way:
[Ctrl]+[Shift]+u
000F
[Enter]
