Encode each character of your text as its 8-bit binary code, space-separated. It maps each Unicode scalar value to a zero-padded byte, which is exact for ASCII. A neat way to visualize how text is stored.

Frequently asked
Is it ASCII only?
Codes above 255 won't fit in 8 bits; stick to ASCII for a clean 8-bit result.
How do I reverse it?
Use Binary → Text on the space-separated groups.
