I want to be able to detect the character encoding of a file without knowing about the file's metadata. Is there a way to do this without looping through every row of a file and looking for characters of a specific encoding?

  • Even Google can't do it for each case, even with looping through every row – Mikhail Ionkin Jul 09 '19 at 20:12

  • You mean you want to guess, based on the current content of the file, right? – Tom Blodget Jul 11 '19 at 04:19
  • Not guess because it has to be accurate. I don't think what I've asked is possible. – Chris Jul 11 '19 at 13:03
  • That is correct. Communicating text means both bytes and character encoding. Often the character encoding is implied or communication on a side channel like HTTP response header Content-Type. But, it is almost never stored with text files (though it could be in some file systems). That said, a text file with the bytes of a Unicode BOM, have a very high probability of being one of the easily distinguished Unicode encodings. – Tom Blodget Jul 13 '19 at 13:47
