Well, in theory, you can -- using the so-called "clean filter" (see the
relevant section of the gitattributes manual page), -- but why should
you?
For instance, how do you know the *input* encoding to be used when
re-encoding? If it's supposed to be the system encoding (and thus it
appears you're using Windows as all sensible POSIX system use UTF-8
by default since ages, or run with encoding-agnostic defaults such as
the "C" locale) then why not just use UTF-8? Any sensible text editor
these days supports it. It might require certain tweaking but writing
a Git filter is way more pain in the neck. The same goes about
indentation--why not just use a specialized tool, like indent [1], for
fixing up the formatting? Or, if IDE is used, just enforce this in its
editor's settings?
As one example, to develop in Go on Windows, I have the following
tweaks in my ~/_vimrc file:
if has("autocmd")
autocmd FileType go setlocal makeprg=go\ build
autocmd BufNewFile *.go setlocal ff=unix|setlocal fenc=utf-8|setlocal nobomb
endif
This forces LF-style line endings, UTF-8 for the file encoding and
forces deleting of byte-order-marks on save.
Another "problem" is that while it's okay to keep the .gitattributes
file in the repository (committed), the filter program is supposed to
be located on each developer's machine.
