I use Active Perl for my Windows based perl/tk scripts. Until
last month, I used perl 5.6 but I have switched recently
to perl 5.8, in order to have the most recent perl/tk
(I needed tk::png for example). And now the problems begin.

1) As you may I have noticed, I am French. So sometimes I
have some directories spelled with french symbols (ç, é,...)
and while it posed no problems with perl 5.6, it does not work
with perl 5.8 (I can't open files located in such directories)

2) I use perlapp to make my scripts executables. Now that I use
perl 5.8 (perlapp not changed), I have the following errors on
stderr when the username on Windows contains french caracters :

Tk::Error: couldn't read bitmap file
"C:\DOCUME~1\FRANOI~1\LOCALS~1\Temp\pdk-François-2096\/Tk/arrowdownwin.xbm ":
No such file or directoryerror reading bitmap file
"C:\DOCUME~1\FRANOI~1\LOCALS~1\Temp\pdk-François-2096\/Tk/arrowdownwin.xbm "
at /PerlApp/Tk/Widget.pm line 205.
  at /PerlApp/Tk/Widget.pm line 203
  Tk callback for .toplevel3
  Tk callback for .toplevel3.browseentry.labentry
  (processing "-bitmap" option)
  Tk callback for .toplevel3.browseentry.button
  <Button-1>
  (command bound to event)

It happens with screens containing browseentry widgets. I have tried to
force the temporary directory with tmpdir switch on perlapp, but it
still creates the pdk-françois subdirectory, so it does not solve anything.

I have been told that perl 5.8 internal encodings are different from
perl 5.6 ones. Is there a way to force perl 5.8 to act "like before"
(especially for widget related issues) ?

Thank you very much in advance for your help, I'm going mad with this
problem :(

Best regards,
