Decode Body from Attachment Object

Question

I'm trying to decode the body field of the Attachment Object in salesforce doing this:

String bodyContent = documento.Body.toString();
Blob bodyDocumentoBlob = EncodingUtil.base64Decode(bodyContent);
bodyDocumento = bodyDocumentoBlob.toString();

When I try it in the application I get this error:

System.StringException: BLOB is not a valid UTF-8 string

Could anybody help me?

Answer 1

Blob only supports files with UTF-8 format.So Please check whether your file is UTF-8 encoded.You will get this error when there are special characters in the file
