setup-config.php breaks UTF-8 in wp-config.php

[SergeyBiryukov]

This code is currently used in setup-config.php to display a wp-config.php content:

foreach( $configFile as $line ) {
	echo htmlentities($line);
}

It makes non-English comments unreadable. It probably should be:

foreach( $configFile as $line ) {
	echo htmlentities($line, ENT_COMPAT, 'UTF-8');
}

Thanks to Lecactus for the report.
