That's okay, you have to translate it to 0x41 (in the general case).
It's no worse than base64, where 'A' means 0x00.
But the idea of "plain text" (as a content TRANSFER ENCODING
not to be confused here with text/plain as a content TYPE) is that I
don't have to do *any* translation. That's my goal. It's fair.
But if the item is in Base 64, I'll just have to decode it.
The 7BIT and 8BIT content-transfer-encodings are "plain text". Yes,
if you get a text/plain content-type with 7BIT or 8BIT encoding,
it's reasonable to simply display them. But if either quoted-printable
or base64 encoding is used, it's not "plain text", and you have to
decode and translate from ascii to the local character set..
