Video SJSON transcripts are supposed to be UTF-8 encoded, but SJSON is an ad hoc thing we made up to make it easier to build the transcripts viewer in the VideoBlock, and it's not well specified. Prior to this commit, if you had an SJSON file with Latin-1 encoded text outside the standard ASCII range (e.g. û), then we'd error out while trying to export it. This was blocking an effort to export some Old Mongo courses (TNL-8007).
