I have read the entire thread until now and (i am sorry) i cant find any
good idea in here.
What we are discussing about? We are talking about 8-bit charset text
streams. Everyone who dealt with - including me - knows: 8-bit char-sets
are .... outdated (very friendly spoken). In case you receive a 8-bit
text file, you probably know nothing about it.
- What codepage was used?
- May be it is a old CP/M textfile where ^Z is used to define the text
end. (CP/M file size is a multiple of 128)
- UTF8 extensions in use?
... and much more Questions how to read the text i cant answer.
There is no and there will never exist a fire-and-forget solution for
reading 8-bit text streams.
I would like to see a lua version working with UTF16. And if someone
want to read 8-bit text, he can convert it - using his knowledge about
the text history - to UTF16. And please dont blame lua for this 8-bit-mess.

I just noticed that io:lines() does not cope with \0 in the lines, and
thus just returns truncated lines (lua-5.2.3, but legacy 5.1 likewise).
May I suggest replacing the call to fgets in src/liolib.c so that we can
read lines with \0 data?
