mintty terminal, python, curses, and utf8 : incorrect display

Question

I've asked here but I'm pretty sure I won't get an answer.

• copy - paste this python code :
• execute it
• in a classical utf8 shell it work properly and displays "Coordonnées" but in my mintty terminal at home it displays "CoordonnM-CM-)es". Any idea how I could make it work, or where I should look (mintty has no character encoding options)?

code:

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os, sys, time, random, copy, pprint
import termios, tty, fcntl
import thread, curses
import locale

def curses_main(stdscr, code):
    curses.curs_set(0)
    stdscr.addstr(2, 0, "Coordonnées")
    stdscr.refresh()
    # (1) = délai d'attente de 1/10 ème de seconde :
    curses.halfdelay(1)
    while True:
        try:
            c=stdscr.getch()
        except:
            c=-1
        if 0<c<256:
            if chr(c) in 'Qq':
                break
def main():
    locale.setlocale(locale.LC_ALL, '')
    code = locale.getpreferredencoding()
    curses.wrapper(curses_main, code)

if __name__ == '__main__':
    main()

Update

Error: I thought found it: it's written everywhere to begin with that code:

locale.setlocale(locale.LC_ALL, '')

so i tried with that and it worked:

locale.setlocale(locale.LC_ALL, 'fr_FR')

=> force it to French language

... it worked but only for the accents. If i try to print line drawing chars:

stdscr.addstr(20,20, "─ │ ┌ ┘ ┐ └ ├ ┤ ┬ ┴ ┼ ═ ║ ╔ ╝ ╗ ╚ ╠ ╣ ╦ ╩ ╬")

gives me:

M-b~T~@ M-b~T~B M-b~T~L M-b~T~X M-...

what is head banging is that vim displays properly those chars. So it seems like it comes... from python? From my Windows/cygwin/mintty that works:

env | grep -i lang
LANG=C.UTF-8

if I force encoding at home in my Windows/cygwin/mintty that doesn't work:

locale.setlocale(locale.LC_ALL, 'C.UTF-8')

this doesn't work.

Any idea where I could look? python seems to override properly the locale settings... the console is properly configured, and the fonts can display line drawing chars, because I see them with vim. So thinking more about it, it may be either a problem of python or a problem of curses...

It's solved. here's what I did: I re-installed cygwin then repacked my python program at work, a re-downloaded it then re-installed minnty 0.9.5.1 (mintty-0.9.5-cygwin17.zip) and it works now. Strange.
