Calligraphy is one of several hobbies I’ve started dabbling with. I’m practicing by writing information sheets for random Unicode characters, which gives me an excuse to share some typographic trivia!

Today’s entry is U+237C RIGHT ANGLE WITH DOWNWARDS ZIGZAG ARROW, also known as angzarr. This is an unusual “ghost character” that until recently, nobody knew the meaning of. Jonathan Chan has an long series of blog posts that eventually traced the character to the measurement of angles.
