/**
 * UTF-8 encoding and decoding.
 *
 * `TextEncoder`/`TextDecoder` exist in every runtime this library targets, but
 * using them would mean either compiling core against the DOM type library —
 * which would let browser-only APIs slip in unnoticed — or shipping ambient
 * global declarations that clash with a consumer's own lib settings. Metadata
 * strings are the only place text conversion is needed, and the amount of code
 * required is small enough that owning it is cheaper than either workaround.
 *
 * Decoding is deliberately lenient: malformed sequences become U+FFFD rather
 * than throwing. Tags come from arbitrary files, and a bad byte in a comment
 * field must never stop the audio from decoding.
