>Description:
Uploading patches to the FreeBSD PR system might corrupt them on download from the PR web page. This affects UTF-8 encoded patches as well as binary patches.

As an additional test I will upload a text containing a UTF-8 snippet, which should resemble two 3 byte uTF-8 sequences forming the word China in Chinese
(0xe4 0xb8 0xad 0xe5 0x9b 0xbd or 中国)

Then I will send a follow up email, that contains the same man page as a mime attachment using content-type application/x-gzip.

I might to additional tests on this PR (more UTF-8 based text etc.) to see if there is a safe way to provide this kind of data to a PR. 

>How-To-Repeat:
Send a bug follow-up containing a gzipped file or UTF-8 file containing special characters.
>Fix:
For binary patches: Copy and paste the base64 representation shown in the PR and decode it on the command line, e.g. using "openssl enc -d -a".

For text: none known.

This might not be a bug and completely work as designed - in this case I would like to see some documentation though, since these days patches might contain UTF-8 characters on a regular basis.
