[mercury-users] ISO-8859-x characters not recognized by MR_GETCH / mercury_getc etc.

[Nick Rudnick]

In fact, my question should be of some interest, as 
io:readline_as_string/1 throws an error every time the input contains an 
ISO-8859-1 character (like äöüÄÜÖß).

Trying to write a patch for this I found out I need some very little, 
stupid support for dealing with mmake, but maybe this is even a simple 
configuration problem.

Any comments are appreciated,

Working with version 0.11 (on Debian 3.0 Woody), I cannot use ISO-8859-x
characters. Is this a configuration issue??

I would like to find out whether anybody else encountered the same 
problem or, better there is somebody to help me in finding a workaround

I stopped my efforts in trying this after getting in trouble with the 
reaction of mmake to changed timestamps of the C files I modified to 
track the problem.

Any advice would be heartily welcome :) , as I try to include Mercury 
into my thesis, what is hardly possible without ISO-8859-x characters.


Thank you in advance,

        Nick

I was quite surprised when finding out mercury throws an error when 
doing text i/o with chars above 0x7F which are common in most languages 
besides English.

As this is not the case with POSIX, this leads me to the question 
whether this limitation is essential to mercury in any way.

In other words - is there a patch possible??

If yes, I believe lots of mercury users around the world would be quite 
thankful to you if you could add this as an installation option, as this 
makes normal text i/o in foreign languages WAY difficult... ;-)
