Why is my Perl program failing with Tie::File and Unicode/UTF-8 encoding?

I am working on a project which deals with data in foreign languages. My Perl scripts were running fine. I then wanted to use Tie::File, since this is a neat concept (and saves time and coding). It seems that Tie:File is failing under Unicode/UTF-8 (unless I am missing something). Here is a program which depicts the problem: (The data is a mix of English, Greek and Hebrew): use strict; use warnings; use 5.014; use Win32::Console; use autodie; use warnings qw< FATAL utf8 >; use Carp; use Carp::Always; use utf8; use feature qw< unicode_strings>; use charnames qw< :full>; use Tie::File; my ($i);

I have the following table structure for a table Player Table Player { Long playerID; Long points; Long rank; } Assuming that the playerID and the points have valid values, can I update the rank for all the players based on the number of points in a single query? If two people have the same number of points, they should tie for the rank. UPDATE: I'm using hibernate using the query suggested as a native query. Hibernate does not like using variables, especially the ':'. Does anyone know of any workarounds? Either by not using variables or working around hibernate's limitation in this case by

Here's a scenario. You have a large amount of legacy scripts, all using a common library. Said scripts use the 'print' statement for diagnostic output. No changes are allowed to the scripts - they range far and wide, have their approvals, and have long since left the fruitful valleys of oversight and control. Now a new need has arrived: logging must now be added to the library. This must be done automatically and transparently, without users of the standard library needing to change their scripts. Common library methods can simply have logging calls added to them; that's the easy part. The
