Is it possible to deactivate this automatic htmlentities() application in the PHP.ini file?

The automatic htmlentities() application in PHP can be deactivated by setting the default_charset directive to an empty value in the php.ini file. This will prevent PHP from automatically applying htmlentities() to all output. To implement this fix, locate the php.ini file on your server and add the following line: default_charset = "".

default_charset = ""
