Stripslashes

If I pass a parameter containing a quote (%27) : https://www.example.com/page/?titre=tes%27t
I get as a result “tes\’t” instead of “tes’t”

On line 80, I recommend setting :

$return = esc_html(stripslashes($rawText));

Instead of :

$return = esc_html($rawText);
