Hi folks this is a serious matter that needs to be addressed ASAP as it cases serious issues like storing empty data in tables!!!
Oxwall DB is not compatible with emojies it either stores them as ???? or pretty much strips entire $_POST content and stores it as empty in table column!
Take a look at replies. Try to add a reply to some newsfeed post using sell phone adding some emojies!
It will return empty reply!!! Why sell phone case those emojies are the ones that case most issues!
The solution requires changing DB charset but I am not an expert in mysql!
