If you only look at one page, this is the one. These are the sets that get copied again and again, because they render almost everywhere and still look like a decision rather than an accident.
Every variation above is made of ordinary characters rather than an installed font, which is what lets the styling travel with the text when you paste it. Put your own words in the box to see them rendered for real, then tap the row you want.
Two things decide whether a style will stick. Some fields โ game rename screens and social handles in particular โ only accept a narrow set of characters and refuse the rest, and a device can only draw the characters its own fonts cover, which is why a style can look slightly different on an iPhone than on an Android. Paste into the real field and look at it there before you save.
