Upside-Down Characters

John Simpson 2020-12-24

A friend saw some “upside down writing” on a social networking site and wanted to know how to do the same thing.

I’ve seen this kind of thing before, it’s just substituting characters which “look” upside down (like “Y” and “⅄”). The trick is knowing what the upside-down version of each character is to begin with.

I pointed my friend to an online converter (I think it was http://www.upsidedowntext.com but there are several out there), but at the same time I decided that I wanted a list of them for myself as well, in case I want to embed them into a web page or something… hence this page.

If it isn’t obvious, all codes below are hexadecimal.
