set emoji crashes nvim, listchars leadmultispace displays wrong symbols

hashtaghashtaghashtag Problem

I have this setting in my init file:

set listchars=tab:<->,eol:$,lead:-,leadmultispace:\|-->,trail:·,extends:>,precedes:<
set emoji

But when I have more than 1 space in front of a word, I get something like this with random kanji symbols:

The last time I know for sure that it worked was with NVIM v0.10.0-dev-e59cf3b3a I know it has been broken for at least a week now. I'm not sure when this error started.

When doing this manually and not loading it from a config file, doing :set emoji or :set noemoji sometimes crashes nvim

hashtaghashtaghashtag Steps to reproduce

1. nvim --clean
2. :set list
3. :set listchars=tab:<->,eol:$,lead:-,leadmultispace:\|-->,trail:·,extends:>,precedes:<
4. type some text, for example

   f
   f    f
   f    

5. :set emoji

You will then either get a segfault or the leadmultispace characters are displayed with random symbols.
