UI: Bugfix. Move to a different TextEncoder/Decoder (#4613)

Browse Source 
1. The previously used TextEncoder/Decoder (used as a polyfill for
browsers that don't have a native version) didn't expose an encoder via
CommonJS. Use a different polyfill that exposes both a decoder and an
encoder.
2. The feature detection itself was flawed. This does a less error prone
detection that ensures native encoding/decoding where available and polyfilled
encoding/decoding where not available.
