If you’re looking for a small tsu on your iPhone, there are a few ways to do it. The first way is to use the keyboard shortcut “cmd-t.” This will type the small tsu character (u+5) into the text field on the keyboard. The second way is to use the “command-option-t” combination. This will type the small tsu character (u+5) into the text field on the keyboard, and then press “option-t” to select it.
