IPC::Run is another possibility:

There isn't a "gb2312 word" in the text. The whole text is gb2312.
You want to distinguish the Chinese characters from the Latin
characters.
I think in GB2312 this is easy: Just search for pairs of bytes with the
high bit set.
But in general I would convert the whole text to Unicode and check the
character properties. This works for *all* encodings, no matter how
complicated they are:
#!/usr/bin/perl
use warnings;
use strict;
binmode STDIN, ":encoding(GB2312)"; # input is GB2312
binmode STDOUT, ":encoding(UTF-8)"; # my terminal is UTF-8
while (read(STDIN, my $char, 1)) {
my $classes = "";
for my $class (qw(Han Latin)) {
if ($char =~ /\p{$class}/) {
$classes .= " $class";
}
}
print "$char - $classes\n";
}
__END__
Prints for a file containing "There is a ä¸å›½äºº in the park." in GB2312:
T - Latin
h - Latin
e - Latin
r - Latin
e - Latin
-
i - Latin
s - Latin
-
a - Latin
-
ä¸ - Han
国 - Han
人 - Han
-
i - Latin
n - Latin
-
t - Latin
h - Latin
e - Latin

p - Latin
a - Latin
r - Latin

gb2312 is a character set, it includes at least Chinese as well as Latin
characters. Therefore all of your text is gb2313, not just that word.
Now, having said that your real task seems to be to distinguish between
Latin/ASCII/.... and non-Latin/ASCII/... characters.
There are several POSIX classes in the regular expressions that will
help you with that, please check 'perldoc perlre' for what is most
suitable for you.

Please Ben, stop messing things up. I said Perl strings, not byte
strings. The unit of Perl strings is characters, not bytes.

That's beside the point. The point is that if a program that formerly
only dealt with byte strings is changed so that SvUTF8 strings are
involved, some important assumptions will be broken. For example, /\w/
will now (sometimes) match more than /[A-Za-z0-9_]/, which is more
likely to be unintended and unwanted than the reverse. For this reason,
if the OP is about to arrange to have his input data converted to SvUTF8
strings, he should read perlunicode so he has some idea of the potential
problems to expect.

If you have
use Tk;
my $main = MainWindow->new( );
$main->protocol( 'WM_DELETE_WINDOW' => sub { print "XXX\n" } );
MainLoop;
then trying to close the window should result in "XXX" getting
printed out instead of closing the window (you would need to
add "$main->destroy" to the subroutine to be executed in order
to get the window also closed). But note that this only works
when the window gets closed in a "gentle" way, i.e. by the win-
dow manager sending it a message asking it to destroy itself
(but I guess that's what most "close buttons" do).

Some more: with

> MainLoop;
the sub will only execute when the close button (or something
similar) of the window manager is used to close the window but
not when you you call "$main->destroy".
If you want to get a sub invoked whenever the window is closed
whatever way you instead should bind the <Destroy> event like
this:
$main->bind( '<Destroy>' => sub { print "YYY\n" if $_[0] == $main } );
Note the check for the first argument the function gets passed:
the sub gets called for each subwidget in the window as it is
destroyed and the first argument is the object getting destroyed.
Thus if you want things to get run once instead for each sub-
widget then you have to return from the sub immediately unless
the argument is the main window.
BTW, there's also the comp.lang.perl.tk newsgroup which might
be an even better place to go to when you have questions about
Perl Tk.

Thanks for your reply.
It probably will help alot.
I will look up the docs for the protocol sub. I am trying to design a
html editor. Do you want me to mail you the source code when I get it
finished?

There's not too much I found, all I did see is from
perldoc Tk::Wm
As far as I understand it the window manager sends a message of
type WM_DELETE_WINDOW to the application (notifying it via an
event of type ClientMessage) when the "close button" is clicked
on (or something similar tells the window manager that the user
wants the window removed) and the application can react to this
message. Most applications just react by to closing the window
(and exiting if this was their only window) but they can do
whatever they want and using
$toplevel->protocol( 'WM_DELETE_WINDOW => sub{ } );
installs a handler for this message to be used instead of the
default.

Hey dude, I see your on your 5th or 7th incarnation of this so called
problem. Several threads later this flat file is in a fixed width form,
but at least its in the same flintstone janra. You should work for WB's
or try upgrading your cable subscription to something other than toon tv.
"I've been pulling my hair out with nested while and do loops...
Here's what I'm working with so far:"
Oh yeah, where is that code you've been laboring and pulling your hair out
on? Below? Don't make me laugh, below is crap junk a 2 year old could scribble.
And this is your output, from your code:
Name: Joe Smith
City: Smallville
Street: 23 Bedrock Road
This is the best line so far in this thread:
"I've included the desired output below."
The only thing you have done is abuse the patrons here and insulted
thier intelligence. Every thread you start on this flat Flinstone file,
with its multiple formats, you have included your desired output.
Unfortunately, your desired output changes as frequently as the
flat file format, as if your trying to write the flintstone format from
pre-determined crap code.
Be honest, you really DON'T have "flat files with many thousands of records",
do you?

Hey dude, you're confused. I'm working with various data files in
various formats. Some are flat files, some are delimited. You should
learn some manners, give up your lame attempts at humor, And learn how

Personally, I don't like using a series of if/elsif blocks when
testing the same var over and over again.
I prefer to use a dispatch table.
This version puts the whole file into the hash, but it's very easy to
add the few extra lines to only store 1 record at a time like Tad
showed.
#!/usr/bin/perl
use strict;
use warnings;
use Data::Dumper;
my %accounts;
my %account =3D (
A =3D> \&Name,
B =3D> \&Children,
C =3D> \&Company,
D =3D> \&OldCompany,
);
while ( <DATA> ) {
chomp;
my $id =3D substr $_, 0, 11;
my $code =3D substr $_, 12, 1;
if ( exists $account{$code} ) {
$account{$code}->($id);
}
else {
warn "code '$code' is invalid\n";
}
}
print Dumper \%accounts;
sub Name {
$accounts{$_[0]}{Name} =3D substr $_, 14, 17;
$accounts{$_[0]}{Street} =3D substr $_, 32, 17;
}
sub Children {
push @{$accounts{$_[0]}{Children}}, substr $_, 14, 17;
}
sub Company {
$accounts{$_[0]}{Company} =3D substr $_, 32, 18;
}

}

You, too. It's "genre". "Genera" is something different.
