DevOps just downloads the file directly from the repo. There are no options to control how files are downloaded.
Things that come to mind:
- Is the file correct in DevOps when you view it?
- If you clone the repo does it copy the file correctly?
- What encoding is the file using?
The file on the left almost looks like it is Unicode but whatever you're looking at it with sees it as ANSI. But this is just a guess based upon the odd spacing.
