Re: change the filetype from binary to text after the file is commited to a git repo

Hey Jeff,

Thx for your answer.

There is no .gitattributes file in the repo. I think that the git heuristic will also detect utf-16 files as binary (in windows), so i think that is the reason why my file is binary (i have to check that tomorrow). If i add a .gitattribute file i have the problem that git diff will treat the old and the new blob as utf-8, which generate garbage.

Do you have another idea?
Could it be possible to add only a space in code (utf-8) and then add the real content in a second commit, so the old and the new one are both utf-8?
