Buffer contents is entirely unrelated to the value of
buffer-file-coding-system.  The latter only determines how to encode
the buffer contents when writing it to a file or sending it to another
process or network connection.

If you get raw bytes in the buffer, the culprit is in the code which
inserted those bytes, or read them from some file.

This is expected when there are raw bytes in the buffer.  The problem
is elsewhere.
