Checker pattern

Depending on which way you do it, this can either be a one-time cat, do nothing, crash certain brainfuck emulators, print start of text, print ■ (or þ depending on the emulator), or do something else I haven't figured out yet.

Nikolas algorithm

This triggers unescapped bracket loops and prints a single character (ASCII 0).
