Encoding issue - question mark output on php script - Raspberry Pi Forums
i've run issue when trying output results of python script web page. getting if run script via command line i'd call normal output, if run same script through website black diamonds question marks displayed in them. there happens differently how files output when run command line vs when run through php? ideas on else should looking at?
stationid.php script calls python script webpage calls stationid.php file <p>to report bug, please file against fpp-vastfmt plugin project here:
