All that was discussed in gnuts, it is not much.

IIRC this is not a bug and squid do not translate in all cases.
Any way the file is marked as a text and any such translation
do not look like a violation. I guess it was done for
convenience of M$ users. IIRC it is impossible to switch this
off in squid (this is the only thing they was wrong).

My point of view that we should not blame the squid, this wouldn't
help. Now I know that there is such problem, you know, a couple
of peoples who will read this. But for the rest the project would
look in the bad way. More over not all peoples can control which
proxy in front of them even if they know about this problem. My
idea was to tech a fetch to request a binary mode for all files
despite of their mime type.
