Re: io:lines() and \0

[Ulrich Schmidt <u.sch.zw@...>]

Hi all.

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 outdated (very friendly spoken).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.

m2c.
Ulrich.
