BUG:Tokenize方法返回的EndIndex比实际下标多1

[agebullhu]

public IEnumerable Tokenize(string text, TokenizerMode mode = TokenizerMode.Default, bool hmm = true)
{
var result = new List();

        var start = 0;
        if (mode == TokenizerMode.Default)
        {
            foreach (var w in Cut(text, hmm: hmm))
            {
                var width = w.Length;
                result.Add(new Token(w, start, start + width));//此处应减1，否则会多包含一个字节
                start += width;
            }
        }
