X-Git-Tag: emacs-28.0.90~6473
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9d0385d7c7adc810dfd06321b783593b7afb3d58;p=emacs.git

Fix problem with 8bit content-transfer-encoding in nndoc mbox files

* lisp/gnus/nndoc.el (nndoc-possibly-change-buffer): If we're
reading an mbox file, it may contain messages that use
content-transfer-encoding 8bit, which means that we have to treat
the file as a sequence of byte (bug#42951).  This avoids
double-decoding -- once by Emacs when inserting the mbox into the
buffer, and once by Gnus when displaying the articles.
