PA text helpers

Wasm bidding scripts need cheap string ↔ bytes conversion to talk to WASM modules. protectedAudience.encodeUtf8 / decodeUtf8 are the new standalone helpers. Round-trip a string below.

Probing…
encoded bytes (length)—
encoded bytes (hex)—
decoded back—
matches TextEncoder?—

the code

// Inside a Protected Audience bidding / scoring script that calls into WASM:
const bytes = protectedAudience.encodeUtf8("Hello, 世界");
// pass bytes into WASM memory, get bytes back, then:
const str = protectedAudience.decodeUtf8(bytes);

// Outside PA, this is the equivalent shim:
const enc = new TextEncoder();
const dec = new TextDecoder();
enc.encode("Hello, 世界");
dec.decode(bytes);
