there is no charset conversion.

+        **raw** (default if --part is given)
+            Write the raw bytes of the given MIME part of a message to

+            If the specified part is a leaf part, this outputs the
+            body of the part after performing content transfer
+            decoding (but no charset conversion). This is suitable for
+            saving attachments, for example.
+
+            For a multipart or message part, the output includes the
+            part headers as well as the body (including all child
+            parts). No decoding is performed because multipart and
+            message parts cannot have non-trivial content transfer
+            encoding. Consumers of this may need to implement MIME
+            decoding and similar functions.
