Issue storing special and latin characters to the databse & Display issue

Hi,

I have one site and on this site, I am using BuddyPress plugin as well. But Now I am facing the issue related to special and the latin character storing into the database as well as displaying Wrongly on the front end.

For Example:

1) ? is displaying like u006f
2) J?rg is displaying like Ju00f6rg

I have also checked my Config file and there is setup like below:

define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ‘utf8_unicode_ci’);

If I remove above two configurations from the config file then I am facing the issue of saving all the data into the database.

Is there anyway to resolve this issue?

Thanks
