Decoding extended ascii base64 stringI have an application that sends a .NET (C#) web service an base64 encoded string. This string sometimes includes extended ascii, e.g. é ù ô and when I try to decode this string in the webservice using: string decodedString = Encoding.UTF8.GetString( Convert.FromBase64String( base64String) ); (string decodes fine if only a-z, A-Z in original string) All the extended ASCII letters are missing, and if I just try to do: Convert.FromBase64String( base64String); The service throws an invalid character error. When I try to decode the string via online decoders, the string decodes fine with all characters so I'm pretty sure the encoded string is correct. Does anyone have any ideas on how I can get the whole decoded string? Any help would be most appreciated! Cheers, Mandy How is the string encoded in the client application? If UTF-8 isn't working
for decoding, it's likely that some other format is being used for the original encoding. You'll need to know what the format is before you can decode properly.
