Block Text Unicode/ASCII [HELP]

[Technological Mastermind]

I've seen this around the web and am wondering how would you make this or how would I make other letters out of this having it only take up one line? Also, how would I make my own Unicode, fully functional and able to use in mobile games, PC games etc. I have used this word in a mobile game for my name and want to make more words with it being compatible with mobile games as well.


Word right here: █▬█ █ ▀█▀ █▄ █ ▄█▀ ▀█▀
