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：
'
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();
}
}
