网页显示音标/拼音显示乱码的解决办法（.net）

为防止音标/拼音在网页上显示乱码，需要对特殊字符进行Asc编码转换，下面是在网页上使用编码后显示文字的方法：

'VB.net
    Public Shared Function ascEncode(ByVal str As String) As String
        If str = String.Empty Then
            Return String.Empty
        Else
            Dim sb As System.Text.StringBuilder = New StringBuilder()
            Dim chars As Char() = str.ToCharArray()
            For i As Integer = 0 To chars.Length - 1
                Dim j As Integer = AscW(chars(i))
                If j > 31 And j < 127 Then '除ASCII 31-127以外进行编码,以防止网页乱码
                    sb.Append(chars(i).ToString())
                Else
                    sb.Append("&#" & j.ToString() & ";")
                End If
            Next
            Return sb.ToString()
        End If
    End Function

//C#
    public static string ascEncode(string str)
    {
        if (str == string.Empty)
        {
            return string.Empty;
        }
        else
        {
            System.Text.StringBuilder sb = new StringBuilder();
            char[] chars = str.ToCharArray();
            for (int i = 0; i <= chars.Length - 1; i++)
            {
                int j = (int)chars[i];
                if (j > 31 & j < 127)//除ASCII 31-127以外进行编码,以防止网页乱码
                {
                    sb.Append(chars[i].ToString());
                }
                else
                {
                    sb.Append("&#" + j.ToString() + ";");
                }
            }
            return sb.ToString();
        }
    }
