You have correctly prepared the code to handle UTF-8 in the source code and input and output operations. What's missing is doing the same for the communication with the database.

By default, DBD::SQLite uses a setting which is wrong (see the documentation for details). To fix it, only slight changes are needed: 

use DBD::SQLite::Constants ':dbd_sqlite_string_mode';

my $dbh = DBI->connect( "dbi:SQLite:dbname=:memory:", "", "",
          {RaiseError => 1,
           AutoCommit => 1,
           sqlite_string_mode => DBD_SQLITE_STRING_MODE_UNICODE_STRICT
          });

PerlMonks is very old and its <code> sections can't handle Unicode. Either use <pre> instead, or replace unicode characters in the source code by their names: 

my $utf8_text1 = "\N{LATIN CAPITAL LETTER A WITH RING ABOVE}ke Lindstr
+\N{LATIN SMALL LETTER O WITH DIAERESIS}m";

BTW, get into the habit of using placeholders to insert values to prevent SQL injection: 

my $insert = $dbh->prepare('INSERT INTO names VALUES(?, ?)');
$insert->execute('nm0512537', $utf8_text1);
