setting those "coding-systems" is somewhat hard to understand (or it is
just me) -- i recall wondering these

  (let ((coding-system-for-read 'no-conversion))

iirc in related code...

One thing could be to wrap the 'links' command in a shell script
which executes 

  exec strace -o /tmp/strace.$$ -e trace=open /path/to/links "$@"'

(name that script as 'links' and point first entry in PATH to the 
directory that exists)

then one can check the logs what is links outputting (i'd guess it
would output utf-8 characters but one cannot know for sure...)
