First, what version of gitweb do you use? It should be in 'Generator'
meta header, or (in older gitweb) in comments in HTML source at the
top of the page.

Second, the file is actually sent to browser 'as is', using binmode :raw
(or at least should be according to my understanding of Perl). And *.bin
binary file gets application/octet-stream mimetype, and doesn't send any
charset info. git.kernel.org should have modern enough gitweb to use this.
Strange...
