Special Character Identification?

Wasn't really sure where do ask about this, but r/hacking seemed like a good place to start. If anyone knows better place to post this, please feel to suggest a sub below. I'm trying to identify some special characters/how these letters work. So I found a guy with a really jacked up name in a multiplayer game, and am trying to figure out what he did. His display name was CactusJack which shows up in game as a different than normal font, and also appears to have spaces in between the letters despite the fact that there are no spaces at all. The game allows no special characters in your username, yet if you copy+paste it into your username area it keeps the funky appearance so however this works is a fun way to beat the system. How does this work? When I highlight the name and copy+paste it into google, it pulls normal search results for "Cactus Jack" like no big deal, despite the search bar and my search history appearing as "CactusJack" What is going on? How and why does this appear as a unique font with spaces?
