Falsehoods programmers believe about text:

- Everybody just uses english text, right?

- Ok, sometimes there might some weird accents or something

- Every character is about the same width

- Well, they're all integer numbers of characters wide

- No character is taller than an english I

- Everybody writes left to right

- Everyone writes horizontally
