[mapserver-users] Encoding issues

[Tamas Szekeres]

You might have to make explicit conversion maually something like:

            string value = "لققافعععىىةةونه"; //I actually get this (in
arabic) through user input
            byte[] bytes = Encoding.Convert(Encoding.Unicode,
Encoding.GetEncoding(1256), Encoding.Unicode.GetBytes(value));
            StringBuilder s = new StringBuilder();
            for (int i = 0; i < bytes.Length; i++)
                s.Append(Convert.ToChar(bytes[i]));
            shpObj.text = s.ToString();

Best regards,

Tamas
