为什么UTF-8字符在jquery textcomplete中不起作用？

Question

我在我的网络应用程序中使用自动完成器jquery-textcomplete。它适用于英语和俄语字母。但它不适用于某些特殊字母，如“ҷ”。

码：

$('.form-control').textcomplete([{
  words: ['тоҷик', 'ҷаҳон', 'english'],
  match: /(^|[^\wа-яёҷ])([\wа-яё]{2,})$/i,
  search: function(term, callback) {
    callback($.map(this.words, function(word) {
      return word.indexOf(term) === 0 ? word : null;
    }));
  },
  index: 2,
  replace: function(word) {
    return '$1' + word + ' ';
  }
}]);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.textcomplete/1.8.4/jquery.textcomplete.min.js"></script>

<textarea class="form-control"></textarea>

这里的词'тоҷик'和'english'正在运作，但'ҷаҳон'不是。我怎样才能解决这个问题？

我需要以下信件才能工作：ғ,ӯ,қ,ҳ,ҷ,ӣ和а-я。
