Copy-and-paste fonts are simple to use and widely misunderstood. Almost every question people ask about them — why text turns into boxes on someone else's phone, why a styled username gets rejected, why a bio suddenly runs out of characters — comes back to the same underlying fact: these are characters, not formatting.
These guides explain that mechanism in plain language and draw the practical conclusions from it, including the ones that are inconvenient. Styled Unicode is not indexed as the letters it resembles, screen readers handle it inconsistently, and some of it will not render for a meaningful share of any audience. Knowing where those limits fall is the difference between text that works and text that quietly fails for the people you were writing for.
