python+ncurses: I can't display accents

[Fabrice DELENTE]

Hello.

I'm trying to display french characters (è -- that's e grave -- or à --
agrave) in python 2.5, with the ncurses wrapper that comes it, and I can't.
My locale is set correctly (fr_FR.iso88591 5), and my terminal (rxvt-unicode)
is able to display those chars.

What am I missing?

Thanks.

What have you tried?

I've tried

stdscr.addstr(0 ,0,"aéïoù")

or

stdscr.addstr(0 ,0,"leçon")

The ASCII chars show correctly, but the accented characters don't, so I see
'ao' or 'leon' on the screen.

The term in which I display is 8-bit-able, so the problem is either on
ncurses side, or on python side.

I have

#!/usr/local/bin/python
#coding: iso8859-15

at the top of my python file.

What happens when you try this?

stdscr.addstr(0 ,0, u"leçon".encode ('iso8859-15'))

I don't really expect it to work, but if anything will, that is
it. Curses supports only ASCII and a some special symbol codes
defined by curses.

I have

#!/usr/local/bin/python
#coding: iso8859-15

Be sure to write your non-ASCII strings as unicode literals, and
then encode them just before displaying or storing them
somewhere.

And it doesn't...

As support for 8-bit (and even unicode) is important for my script, is there
any hope? Should I switch to slang instead of curses?

un - no. Curses supports whatever the flavor of curses you have does.
Often that's the 8-bit flavor of ncurses, but the limitation is definitely
in the python configuration.

My system is Linux, and the distribution is Slackware 10.1.

I have

/lib/libncurses.so.5 .4
/lib/libncursesw.so. 5.4

so I even have the wide-chars version available. Any hint on the python
configuration? I didn't find any function that would allow the unrestricted
display of 8-bit chars.

Thanks for the clarification. I was going by the some Python
documentation, but I did notice contradictory information in
other discussion. The 8-bit ncurses is supposed to support
iso-8859-1 through iso-8859-15, i.e., all the byle encodings. I
don't know why Python's bindings don't work.

To really be sure that the problem is when I use python, I tried in C:

#include <stdio.h>
#include <ncurses.h>

int main(void)
{
initscr(); /* Start curses mode */
// printw("àéïoù") ; /* Print Hello World */
addstr("àéïoù") ; /* Print Hello World */
refresh(); /* Print it on to the real screen */
getch(); /* Wait for user input */
endwin(); /* End curses mode */

return(0);
}

and both my tries (with printw, or with addstr) showed the 8-bot chars
correctly.

Incidentally, I noticed something about the environment: in my script, I use
the LINES and COLUMNS environment vars that are set in my shell:

columns=int(os. environ.get("CO LUMNS"))
lines=int(os.en viron.get("LINE S"))

In the shell, I get

$ echo $LINES $COLUMNS
89 199

but python doesn't get these values. I have to start the script with

$ LINES=$LINES COLUMNS=$COLUMN S ./sort_entries.py

How come?
