Decorations vs letters
Some styles here change the letters (Typewriter, Double-struck, Greek-ish). Others keep the letters and wrap them in symbols (โง๏ฝฅ๏พ sparkles, ๊งเผบ wings เผป๊ง). The decorations come from Javanese punctuation, Tibetan marks and Japanese half-width katakana, which is why they add several characters each.
