Here's a website I found that will produce upside down versions of any English text.
how does it work? does unicode have upside down chars? Or what?
How can I write my own text flipping function?
does unicode have upside down chars?
Yup! Or at least characters that look like they are upside down. Also, regular English-alphabetical characters can appear to be upside down. Like u could be an upside-down n.
To code it up, you just have to take an array of characters, display them in reverse order and replace those characters with the upside down version of them. This will get you a good start: zʎxʍʌnʇsɹbdouɯןʞſıɥbɟǝpɔqɐ
