Change the message's font. You have several potential font-changing options available:[1]
To bold text, type an asterisk * at the beginning and end of the message. For example, *Hello!* would become Hello!
To italicize text, type an underscore _ at the beginning and end of the message. For example, _How are you?_ would become How are you?
To add a strikethrough (a line through the text), type a tilde ~ at the beginning and end of the message (e.g., ~I made a typo~).

Use the FixedSys font. By typing three backquotes (apostrophes ``` which slant downward from left to right) before and after the message, you can unlock a secret font which resembles the text style used in Command Prompt and Terminal.
For example, ```Computers will conquer mankind``` would become Computers will conquer mankind when sent.
On an iPhone, you'll have to tap the 123 button on the keyboard, tap and hold the apostrophe ' key, and select the left-most option in the resulting pop-up menu to type a back quote.
