Leaving the content at 8bit is fine though somewhat limiting (splitting
long lines, portability problems with buggy intermediate MTAs, ...), the
key is to use a charset that includes ASCII as an identity encoded subset.

I would personally recommend quoted-printable for 8bit text, but this is
optional, so long as the charset is correct. Note that including an 8bit
text/plain entity contained in a multipart/report, requires a content
transfer encoding of "8bit" also for the enclosing multipart/report
message.
