1. Font unicode-range subsetting

    This @font-face descriptor defines the set of Unicode codepoints that may be supported by the font face for which it is declared. The descriptor value is a comma-delimited list of Unicode range (<urange>) values. The union of these ranges defines the set of codepoints that serves as a hint for user agents when deciding whether or not to download a font resource for a given text run.

  2. KeyboardEvent.charCode

    A legacy `KeyboardEvent` property that gives the Unicode codepoint number of a character key pressed during a `keypress` event.

  3. KeyboardEvent.code

    A `KeyboardEvent` property representing the physical key that was pressed, ignoring the keyboard layout and ignoring whether any modifier keys were active.

  4. TextEncoder & TextDecoder

    `TextEncoder` encodes a JavaScript string into bytes using the UTF-8 encoding and returns the resulting `Uint8Array` of those bytes. `TextDecoder` does the reverse.

  5. WebCodecs API

    API to provide more control over the encoding and decoding of audio, video, and images.
