We're currently upgrading one of our 1.4.12 installations up to 1.5.8, before we upgrade to 1.6.5.
Under 1.4.12, we have the setting "$wgUseLatin1 = false;" in LocalSettings.php, which the help page http://www.mediawiki.org/wiki/Help:$wgUseLatin1 (very) briefly describes as "Enable ISO-8859-1 compatibility mode".
Is this still necessary under 1.5.8? The help page says it's still in use, but it was not in the default 1.5 LocalSettings.php file.
Thanks, -Jeff
