从文本文件中删除重音符号 [英] Remove accents from a text file

问题描述

我在从文本文件程序中删除重音符号时遇到问题，用变音符号将字符替换为?这是我的代码:

I have issues with removing accents from a text file program replaces characters with diacritics to ? Here is my code:

        private void button3_Click(object sender, EventArgs e)
        {

           if (radioButton3.Checked)
            {
                byte[] tmp;
                tmp = System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(richTextBox1.Text);
                richTextBox2.Text = System.Text.Encoding.UTF8.GetString(tmp);


            }

        }

推荐答案

richTextBox1.Text = "včľťšľžšžščýščýťčáčáčťáčáťýčťž";            

string text1 = richTextBox1.Text.Normalize(NormalizationForm.FormD);

string pattern = @"\p{M}";
string text2 = Regex.Replace(text1, pattern, "�");

richTextBox2.Text = text2;

首先规范化字符串.
然后用正则表达式替换所有变音符号.模式 \ p {M} 是 Unicode类别-所有变音符号.

First normalize the string.
Then with a regular expression replace all diacritics. Pattern \p{M} is Unicode Category - All diacritic marks.
