Thanks, I installed it.

encoded_file is in UTF-8 on your system.  What you perceive as "messy
code" is how Emacs displays unibyte strings, which are actually
sequences of raw bytes, not of characters.

utf-8 and utf-8-hfs are not exactly the same, but for Chinese
characters they produce the same results, because those characters
don't have decompositions.
