This is what i believe is not happening.

Lets do this with a public repository and steps which are reproducible.
I have created a repo : https://github.com/ashishnegi/git_encoding

If you clone this repo in linux and run `git status`, you will find
that file is modified.

About repo :
Repo have 2 commits, done on windows machine.
First one check in a utf-16le encoded file which has crlf. crlf will
not be converted to lf in index as git treats it as binary file.
2nd commit changes encoding to utf-8 and commits.
This commit does not change crlf to lf in index, even though new
format is utf-8 which is text based for git. This is the crux of
problem.

I have attached all commands i ran on windows while creating the repo.
I tried to capture all information that i could give.
Please have a look. It might be useful.

Finally, thank you Torsten for giving your time to the problem. Really
appreciate it.
