Bareword issue with Perl 5.34

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks

Loading the following does not produce any issue with Perl 5.28.

use strict;
use warnings;
$Win32::OLE::CP = CP_UTF8;
[download]

It produces issues however with Perl 5.34:

Bareword "CP_UTF8" not allowed while "strict subs" in use at test.pl l
+ine 3.
Execution of test.pl aborted due to compilation errors.
[download]

Changing $Win32::OLE::CP = CP_UTF8; to $Win32::OLE::CP = 'CP_UTF8'; avoid Perl complaining, however the feature is no more loaded. What is the best approach to solve this?
