[ambrus]: Dumu: why would you want to read the same file both in binary mode and utf8 mode?
[Corion]: Dumu: Yes, but switching needs to be done with caution, as you might read half an UTF-8 character in binary mode, and then switch to utf8 mode...
[Corion]: Personally, I would do the decoding of data in the program and not in the filehandle
[Corion]: ambrus: Maybe a record-based file where some data is strings encoded as utf8
[Corion]: But again, I would read all data as binary and then decode from utf8
[ambrus]: Corion: that wouldn't be my guess, but I'll wait for Dumu
[Corion]: Meh. I'm now on Firefox 57 ("Quantum") and again have to remove Pocket, and reinstall the adblocker, uMatrix (because NoScript doesn't work) and silence the about:blank page to not download crap from the internet
[Corion]: Maybe I shouldn't update software ...
[ambrus]: Corion: my guess is to first read the start of the file to check what format it is out of two or more possibilities, then rewind it and handle it differently depending on the program
[ambrus]: s/program/format/
