				$sentence = preg_replace( $flag_no_digit, $close_quote, $sentence, -1, $count2 );
				if ( 0 === $count2 ) {
					// Try looking for a quote followed by a period.
					$count2 = substr_count( $sentence, "$flag." );
					if ( $count2 > 0 ) {
// Assume the rightmost quote-period match is the end of quotation.
$pos = strrpos( $sentence, "$flag." );
					} else {
// When all else fails, make the rightmost candidate a closing quote.
// This is most likely to be problematic in the context of bug
