new tag korean not working!

[boxfox619]

i try use ng2-select2 with this options
{ tags: true, maximumInputLength: 15, multiple: true, width: '100%', placeholder: 'text' }

and write new tag like "한글", this is korean,
but, the tag inserted like this. "ㄹㄱㅡㄴ하"

I tried solve this with changing the options. and i find the tags options is problem.
This problem occurred when tags is true and multiple is true,

I can't solve this problem
Would you help me please?
