Answer 1

For someone using Visual Studio seeing the annoying red dot on bitbucket on 2018, just go to Visual Studio to "File" -> "File.cshtml Save As..." and select "Save with Encoding...":

Then it will popup a screen so that you can change the Encoding, try and look all the way down in the list until you see "Unicode (UTF-8 without signature) - Codepage 65001":

After this, just overwrite your file and upload it to your repo and the BOM will be gone.
