What if you evaluate this first:
(set-default-coding-systems 'utf-8-dos)
Does it still work for you? The OP is on MS-Windows, where the
default decodes the CRFL EOLs, something we shouldn't do with image
data.
In general, I believe explicitly binding coding-system-for-read, as
the OP suggested, is better than relying on some code somewhere that
just happens to let this work (on some systems).
