Bitbucket has trouble viewing files with UTF-16

XMLWordPrintable

      Bitbucket seems to have trouble viewing and diffing files of various encodings.
      I created a git repo, committed a bunch of files with different encodings, then attempted to view them via the file browser in Bitbucket. Some of the files render with a special character shown, some don't render at all.

      Then I branched, made changes to each file, committed and made a pull request. Most of the files had trouble rendering in the diff and instead bitbucket showed "This file cannot be rendered in your browser".

      Here's some results. I've attached the git repository that I originally uploaded to our Bitbucket instance to perform the tests.

      File Encoding Result file command result
      test-utf8.txt UTF-8 Good ASCII text, with CRLF line terminators
      test-utf8bom.txt UTF-8 with BOM Displays \ufeff char at beginning of direct view, and during pull request diff. Diff renders correct otherwise UTF-8 Unicode (with BOM) text, with CRLF line terminators
      test-utf16le.txt UTF-16 LE Can't be displayed directly nor can it be displayed in pull request diff data
      test-utf16lebom.txt UTF-16 LE with BOM Displays \ufeff char at beginning of direct view. Diff renders only if transcoding is enabled. Little-endian UTF-16 Unicode text, with CRLF line terminators
      test-utf16be.txt UTF-16 BE Can't be displayed directly nor can it be displayed in pull request diff data
      test-utf16bebom.txt UTF-16 BE with BOM Displays \ufeff char at beginning of direct view. Diff renders only if transcoding is enabled. Big-endian UTF-16 Unicode text, with CRLF line terminators
