Hi, what is your Vim version?
I use syntax iskeyword to do this now.
It requires 7.4-1142

@othree Hi, I am currently using neovim. Perhaps the problem was with neovim?

[othree]

Sorry, I am not sure which version of nvim supports this feature.
Can you try execute manually:

syn iskeyword @,48-57,_,192-255,$

[ycmjason]

I have tried it, confirming that it will work!

[othree]

What do you mean work. The highlight works after you execute the command?

@othree

Yes. After running your suggested command: syn iskeyword @,48-57,_,192-255,$ the highlight is correct.
