php - American apostrophe clears form input -

-

’ kind of apostrophe ruins input saved database. i've tried 

$generalchangedescriptions[$championnumber+1][$indexgeneral+1]=str_replace("’", "'",    $generalchangedescriptions[$championnumber+1][$indexgeneral+1]);

so changing ’ ' no results still empty field. value apostrophe shown fine after sending with

 <input type="hidden" name="generalchangedescriptions" value="'.htmlspecialchars(json_encode($generalchangedescriptions)).'">

it no longer visible whole input blank there way fix this?

update:

after fiddling bit code found out json_encode wipes input after sending there easy solutions?
