Dice can be useful to randomize letters, say, when you’re making a cipher, or trying to write fantasy or science fiction proper names. Ojmwrgm, the pirate, for example.
Unless you’re trying for something like Drizzt. Or any other name requiring a Q, U, V, X, Y or Z. This is just a 20-sided die, after all. (Though they keep the C, K and S, when they could have left out the C as redundant. English is weird.)

Perhaps I will try that when next I need a fantasy name haha. But I don’t know how I feel about the missing letters… alas, the failings of an icosahedron.

Indeed, it’s not a particularly elegant solution. A D30 might be better, with the extra four faces as punctuation or umlauts or the like.
Quite true. Or maybe instead of punctuation you could just add doubles of letters that seem like they fit most into the language/naming conventions of the fantasy segment your character comes from.

Indeed. Hrm… might be a reason to design another D30 beside that gearpunk one I did. 🙂
