"Mirror image glyphs occur when flipping one character creates another"

About a half of the article is about these "mirror image glyphs". Why would they be a problem for the proclaimed purpose of character distinction? Has anyone ever mixed up "b" and "q"?

This is a fair question/critique. As I understand it, this is a particular consideration for coders and readers with dyslexia, as they flip the letters. The thought process is that by making the characters distinct, it reduces this problem.

I learned about mirror glyphs through a document linked in the Accessible Perceptual Contrast Algorithm (APCA) website. For context, APCA is the system that aims to supplant current color calculation methods in the Web Content Accessibility Guidelines (WCAG).

Only when reading books to my children and we sit on the ground and the book is upside down for me :-). When programming, not once.

The real reason it’s important is that for some the glyphs are too much alike and can be confused. The brain may rotate of flips things sometimes.
