Re: Tk causes problems with file paths containing non-Latin-1 chars

[lamprecht]

This should work on Win32:

use warnings;
use strict;
use Tk;

if ($^O =~ /Win32/){
    my $gof_wrapped = \&Tk::getOpenFile;
    *Tk::getOpenFile = sub{my $file = shift->$gof_wrapped;
                           return Win32::GetANSIPathName($file)};
}

my $mw = tkinit;
my $path = $mw->getOpenFile();
open (my $fh, '<', $path) or die "can not open file $path : $!";

while (my $line = <$fh>) {
    print $line;
}

close $fh;

MainLoop;

Thanks! That fixes the problem in my test code. Refactoring the app will be a bit more complex, but it looks do-able.

The changes to the test program so it will run under Linux|OS-X|Win32 are:

...
use if ($^O =~ m/MSWin32/i || ''), 'Win32';
...
my $is_win32 = $^O =~ m/MSWIN32/i;
...
sub test_file
{
  my $file = ucx(shift);
  ...
}

sub ucx
{
  my $fn = shift;
  return $is_win32 ? Win32::GetANSIPathName($fn) : decode('utf8', $fn)
+;
}

Out of curiosity, I went looking for the GetANSIPathName method in the ActiveState (win32) lib code. As far as I could see, it's not a Perl function, so I guess it must be all in a dll someplace.

For anyone who wants to play with this, a zip of the code and data can be downloaded from http://itee.uq.edu.au/~chernich/downloads/tkbug.zip.
