在分支之间切换会导致变化

Question

When I switch between branches, it causes changes on the branch that I switch to, and the changes is always to random files. When looking at the changes, there is nothing different but it is insisting that something has changed. When I undo changes, it doesn't do anything. The only thing I can do to proceed is to commit those files, then continue working.

Also committing png and zip files causes the files to become corrupt on the git repo, so others who sync will get messed up files.

I thought it might be to do with the line-endings, but I'm fairly new to git and not sure how to resolve this random issue. Any ideas?

Here is a git diff of a file that shows changes:

diff --git a/Presentation/Emails.vb b/Presentation/Emails.vb
index a767a0d..91e9613 100644
--- a/Presentation/Emails.vb
+++ b/Presentation/Emails.vb
@@ -1,351 +1,351 @@
-<U+FEFF>Imports System.Data
-Imports System.Web
-
....rest of the file

I notice it has "U+FEFF" at the start, what does this mean?

Make sure that git config core.autocrlf is set to false.
If not, it will mess up binary files, trying to change "end-of-line" character sequences which are not "eol" in said binary.
