Emoji not visible when copied from one table to another in Mysql

Question

I have text with emojis in a sql table. Collation is set to utf8mb4_bin. The mobile app reads the emoji from table and displays correctly. It inserts the emojis properly.

Using dashboard, sometimes I copy this text to another table with same column and collation. But emoji from this table is not visible in mobile app. I see only ????????

Why so?

Where was "collation" set to that?? – Rick James Oct 17 '16 at 20:54 — Rick James, Oct 17 '16 at 20:54

Question Marks (regular ones, not black diamonds) (Se?or for Señor):

The bytes to be stored are not encoded as utf8/utf8mb4. Fix this.
The column in the database is CHARACTER SET utf8 (or utf8mb4). Fix this.
Also, check that the connection during reading is UTF-8.

I finally cracked it. It was an issue with database connection of the dashboard from where I was copying data from one table to another. the connection encoding was set to utf8. I changed it to utf8mb4.
