Can SourceTree diff markdown with file extension .md or .markdown?

[S Baker]

I'm using Xcode and GitHub, would like SourceTree to diff README.md.

SourcTree says it's a binary file, doesn't display a diff.

The problem is likely that you've encoded the file as UTF-16. Git and Mercurial can only diff/merge UTF-8 text files.

Thanks! In Xcode File Inspector I converted encoding from UTF-16 to UTF-8 and now when I edit the file SourceTree shows the diff.

I think this might have something to do with file associations, because I'm using both .markdown/.md file types and SourceTree displays them fine for me. Could you change the "Always Open With" option on both markdown/md files? (Ctrl+click -> Open With -> Other -> check "Always Open With" and pick say, textedit?)
