I am not sure if this happens with other keyboards but I found a bug when deleting emoji with backspace. It deletes an emoji but replaces it with this symbol: �����.
When I try to delete the very symbol, it reproduces it again by three.
If I try to delete this …
Backspace once produces ���
Three times �������
I cannot delete those unless I use another non-keyman keyboard.
The emoji are from default or other installed keyboards or WhatsApp embedded. My keyboard does not have emoji.
Anyone has an thought?
