Unicode, Perl and SQLite database on Debian Linux

As shown below, the green line is the one for telling SQLite to use Unicode in perl. This is useful especially if I need to use Chinese, Korean, Japanese or other non-English characters.



#!/usr/bin/perl -w

# load module
use strict;
use utf8;
use encoding "utf-8";
use DBI;




    my $SQLiteDB = DBI->connect( "dbi:SQLite:dbname=myDB.db", "", "" );
     $SQLiteDB->{sqlite_unicode} = 1;
    my $x = '';


   my $sth =  $SQLiteDB->prepare("SELECT count(*) FROM TABLEX LIMIT 1");
    $sth->execute();

     while(my $ref = $sth->fetchrow_hashref()) {
       $x = $ref->{'count(*)'} ;
    } # while(my $ref = $sth->fetchrow_hashref())
