I have two files, of .cs type. Their codepage is UTF-8. If I compare the files directly, everything looks fine. If however I compare the folders containing the files and double-click a file to do a comparison, when the file opens non-ascii characters (like Greek) don't appear correctly and there's a ο» added to the beginning, which is a sign that WinMerge doesn't understand the file's codepage.
I suppose this is a bug, but is there a way to work around it?
