从文件中读取每个非英文字符

Question

假设一个文件包含非英文文本。我们可以使用 FileIO.ReadLinesAsync 方法读取文件内容。现在每一行都包含一组字符。如何从此字符串中提取每个字母（非英文字母）？在这里，我用 C# 代码表示了我的问题。

   List<string> finalAlphabets = new List<string>();
        IList<string> alphabetLines = await FileIO.ReadLinesAsync(_languageFile,UnicodeEncoding.Utf8);
        if (alphabetLines.Count != 0)
        {
            foreach (string alphabetLine in alphabetLines)
            {
                //lets say alphabetLine has "కాకికు", here i want to extract each letter from this and i want to add to finalAlphabets list 
                finalAlphabets.Add("కా"); // How to extract this letter from alphabetLine variable. If you look at the Length of alphabetLine , it shows 6, but actually in Telugu language it is 3 letter word.             
            }
        }

Answer 1

有一组文本信息类 - TextInfo、StringInfo，特别是您可能正在寻找 TextElementEnumerator，它可以让您找到 "text element"边界。

来自 MSDN 文章的简化示例：

var myTEE = System.Globalization.StringInfo.GetTextElementEnumerator( "కాకికు");
while (myTEE.MoveNext())  {
     Console.WriteLine( "[{0}]:\t{1}\t{2}", 
         myTEE.ElementIndex, myTEE.Current, myTEE.GetTextElement() );
}

产生以下输出：

[0]:  కా  కా
[2]:  కి  కి
[4]:  కు  కు
