Decode Unicode escape notation into the represented characters.
The frame below runs the same code as this page, in the reader's own browser. Nothing is sent to us, and nothing is sent to you.
Pick a dark background and the text and panels follow it, so the frame stays readable on a dark page.
Unicode escape notation is converted into UTF-16 code units or a Unicode scalar value, depending on whether the source uses four-digit or brace code-point syntax. Valid surrogate pairs combine into one displayed character during rendering.
