Ok heres the script I used to generate unicode file:
Look Ok?
##############################
my $ustring = "Hello \x{263A}!\n";
binmode STDOUT, ":utf8";
open FILE, ">:utf8", "OUT.txt";
print FILE "$ustring1$ustring2";
close(FILE);
# prove it
print "$ustring1$ustring2";
# prove it again
open FILE, "<:utf8", "OUT.txt";
@file = (<FILE>);
print @file;
close(FILE);
##############################
Then I read the file and put in textctrl& listbox and it looked good.
Also print to STDOUT correctly - AND I did NOT have to use
the 'perl -C' or :utf8 encoding for things to work.
So I guess it is the strings that are being bad.
BUT how come the bad data show correctly on the command line if I use 'perl -C'?
And show correctly in Tk ?
I cannot modify the data - not my data. What can I do to correct
or atleast get something other than a blank string ?
Thanks again.

What do you mean exactly when you say unicode? What is the used encoding? UTF-8?
Here are some ideas:
- Did you test Mattia's suggestion? Unicode and databases are known to cause
weird troubles that are hard to identify
- Try creating a test app and let it read from a test textfile of which you are sure that it's UTF-8
encoded ( maybe even create it with something like open(my $fh, ">:encoding(UTF-8)",
"test.txt")
- As you mentioned in another reply, font can most definitely be a culprit.
Lots of (older) fonts can't display characters beyond the ascii or latin-1 set.
Don't ditch wxPerl yet. It really is a powerful versatile toolset.

Huub

Trying to move off perltk and the new Guis are looking good, but if we can not
display
unicode characters wxperl is dead for us :-(

Heres are some print statement output when running app:

perl -C uwi_flip.pl
Well ==> HENW_Letebrønner
Any names with these characters in them do not display in widgets - they are
blank.
No errors, just blank. The wxwidgets .so should be unicode.
Yes, they are.
What am I missing ?????
Are you sure that the strings you read from the database have the Unicode
flag set when read from the database? You can use the Dump() function from
Devel::Peek to check if the scalar has the Unicode bit set.
If the Unicode bit is not set on the scalar, the conversion from Perl scalar
to wxString should use the encoding of your current locale, but I can't
remember if if uses the system locale or (more likely) the locale set with
wxLocale.
