Characters being rendered with replacements

I saw this when migrating from b2 to WordPress. It has to do with smart quotes being present in the original data. WP doesn’t seem to like this (it has its own built-in smart quote conversion that handles this during rendering.)

I’m in the process of completing the migration script I’m writing for b2 to WP and will release it when its done. In the meanwhile, though, here’s the code I’m using the get rid of this issue:

// Convert smart quotes to simple quotes
function smartToSimpleQuotes ( $str )
{
$str = str_replace(‘“’, ‘\”‘, $str);
$str = str_replace(‘”’, ‘\”‘, $str);
$str = str_replace(‘‘’, “\'”, $str);
$str = str_replace(‘’’, “\'”, $str);

return $str;
}

(That function, run on each post, during migration.)
