## Summary
- use `StringDecoder` to decode stream content safely across chunk
boundaries
- add tests for JSON and text bodies with UTF-8 characters split between
chunks

  ## Problem
Direct `chunk.toString()` decoding can corrupt UTF-8 characters when
multi-byte sequences are split across stream chunks.

  ## Testing
  - added unit tests for chunk-boundary UTF-8 decoding in JSON body
  - added unit tests for chunk-boundary UTF-8 decoding in text body

## Summary by CodeRabbit

* **Bug Fixes**
* Improved UTF‑8 decoding for streamed request bodies so multi‑byte
characters split across chunks are decoded correctly and incomplete
final bytes are handled gracefully (replacement character used).

* **Tests**
* Added tests validating JSON and plain‑text payloads with multi‑byte
UTF‑8 characters split across stream boundaries, including an incomplete
final byte scenario.
