Ok, I think I am slowly loosing my sanity...

I tried both f.contents and f.value, both are undefined in Seed and Gjs
(Gjs seems to print the file plus some stuff when doing print(f))

Possibly, as it is from IRC there is potentially everything in there,
with everybody using a different encoding.

I tried the same file with Python, decoding as UTF-8 fails there as
well, so this is the file that's broken. Reading it linewise and
figuring out what the encoding of the line is, sounds like the best bet.

That actually works for me as well (and is similar to what I started
with, except that I did not know about c_new), but only on Seed. Gjs
seems to require some more arguments to read(), read_line() and can't
instantiate DataInputStream :/
