Subject: Re: [Bugme-new] [Bug 9319] New: National characters are not displayed
 under console.

This isn't a regression.  It's an intentional default change.

The default console mode changed from 8-bit legacy to UTF-8 in 2.6.24.

Apparently this user is using a legacy character set (note that it's a 
Slackware machine), and isn't explicitly setting the character set via 
the appropriate escape sequence.

The new default can be overridden via 
/sys/module/vt/parameters/default_utf8 or something like that...
