The problem seems to be not so much with the encoding as with your attitude toward it. With each new post on this same topic, you seem to be telling us you are not learning what you need to learn, and you appear to have a deliberate resistance to learning.
The OS you are using (the particular version of MS-Windows on your machine) is storing file names in directories using CP1253. Get used to that. Deal with it.
The content inside the files -- that is, the character encoding used for the text data -- might or might not be under your direct control, and might vary from one file to the next. Figure out some minimal diagnostic that you can use on any given data file to work out which encoding it uses. This is not so difficult when the likely alternatives are either utf8 or CP1253.
Use the diagnostic in your cgi script if you have to, but better yet, use it as a separate sanity check on file contents on some regular basis: choose one encoding that would be most convenient in general, and run a stand-alone process on your data files that will check whether the text content uses that encoding. If you find files that use the "wrong" encoding, convert them to the "right" encoding (i.e. whichever one you've chosen as your "standard").
You'll probably be better off you you decide that file contents (text data) should be in utf8; you could use this tool I posted a while back to diagnose the utf8 content of data files, and see what sorts of problems you might be having with that. Other tools are probably available as well -- try googling for "utf8 validation".
You might recall that in one of your previous threads, I suggested a custom module for you (I called it "GreekFile.pm"); if you store that module in the same place as your cgi script, you could write your cgi script like this (at least, based on the parts of the code posted above that made sense):
use GreekFile qw/gr_glob gr_open/;
binmode STDERR, ":utf8"; # might help for error reporting
# ...
my @files = gr_glob( "../data/text/*.txt" ); # @files is an array of u
+tf8 strings
# because the gr_glob function in GreekFile.pm handles that conversi
+on
my %display_files; # let's store file names in a hash
for ( @files ) {
my $f = $_;
$f =~ s/\.txt//;
$display_files{$f} = $_; # use hash keys for display, hash values
+ as file paths
}
# ...
my $passage = param( 'select' ) || "blah blah (in Greek)";
# $passage is assumed to be in utf8
if ( exists( $display_files{$passage} ))
{
gr_open( FILE, "<:utf8", $display_files{$passage} )
or die "$0: $display_files{$passage}: $!";
local $/;
my $data = <FILE>; # $data is assumed to be utf8
# ... do stuff with $data ...
}
Notice how the cgi app does not need to worry about encoding the file names to CP1253 -- the "GreekFile" module handles that. (Bear in mind that I did not test the module thoroughly -- I don't have an MS-Windows system, let alone one that stores file names with CP1253 characters.
Also notice the extra care in the error report for "die" -- this makes it easier to look for evidence in the web server's error log. (You do look at the error log, don't you?)
If you are going to reply again that this is too hard and confusing, you might as well get another job. |
