How could I add text like this

& how could I add more of these

 

It's Hive's texturepack for ScoreHud
it's public so good luck finding it

 

It's a hive texture that modifies the scoreboard to the top and adds these unicode images, you can get it from a mobile phone with ROOT or a computer with Minecraft Windows10, and to add and in the same way you do with the normal scoreboard...

 

thanks
