Input.TextReset

// If you need to read text input directly from a soft or hard keyboard,
// these functions give you direct access to the stream of Unicode
// characters produced! These characters are language and keyboard layout
// sensitive, making these functions the correct ones for working with text
// content vs. the `Input.Key` functions, which are not language specific.
//
// Every frame, `Input.TextConsume` will have a list of new characters that
// have been pressed or submitted to the app. Reading them will "consume"
// them, making them unavailable to anything that comes after. If you need
// to bypass some earlier element consuming them, you can reset the current
// frame's consume queue with `Input.TextReset`.
