Support multibye charactor / unicode

[tkkcc]

Hi,

It seems this plugin doesn't support multibyte charactor, for example 图片。I tried modifying

function source:get_keyword_pattern()
  return [[\w\+]]
end

to [[\k\+]], but failed.

Currently, multibyte charactor is support in buffer source using

sources = cmp.config.sources({
  {name = 'snippy'}, {name = 'nvim_lsp'},
  {name = 'buffer', option = { keyword_pattern = [[\k\+]]}},
  {name = 'path'},
  {name = 'tmux'},
}),

Sorry for the late reply. I've been really busy all day 😅

Thanks. I'll do some investigation on this.

I figured out that this is a problem because of the internal Lua string matching functionality.

This can be solved by tapping into the Neovim multibyte APIs. Gotta do a bit of research on that and I'll open a PR with a solution to test.
