Here's a 62 char solution, imploying half a schwatzian transform:
sub g{ #234567890123456789012345678901234567890123456789012345678901234567890 my$c=pop;(sort{@$a[1]<=>@$b[1]}map{[$_,abs($_-$c)]}@_)[0]->[0] }

[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/
[Dumu]: ambrus: it's about testing a file for being multiple possible file formats
[ambrus]: In particular, you might want to detect the encoding of a HTML file from between utf-16 versus ascii-based and encoding given in a META tag.
[ambrus]: Dumu: it should probably be safe to change the encoding if you rewind first with seek $file, 0, 0 first
[Dumu]: ambrus: good guess. I'm trying to contribute to a CPAN module, and the existing tests assume they're looking at text files
