@react-native-quickjs/text-encoding

TextEncoder and TextDecoder, per WHATWG Encoding, as direct QuickJS bindings.

Hermes provides both, so an app moving to QuickJS expects them. Without them a bundle either carries a JavaScript polyfill -- the encoder is a per-character loop over a growing array -- or fails outright: Expo's development client reads TextEncoder while loading, before any app code runs.

@react-native-quickjs/quickjs depends on this package, so an app gets it without asking.

Behaviour worth knowing

• An unpaired surrogate encodes as U+FFFD; it is not an error.
• A leading byte order mark is stripped unless ignoreBOM is set.
• fatal: true throws a TypeError on ill-formed input; otherwise ill-formed sequences decode to U+FFFD.
• encodeInto stops on a character boundary, so a destination too small for the next character consumes nothing rather than writing a partial sequence.
