When encoding large JSON strings tagged as semantic_tag::noesc, json_encoder currently writes characters one-by-one via sink_.push_back(*it). This is a hot path for payloads dominated by large base64 fields and causes a noticeable regression versus previous versions.
This gives significant improvement on noesc-heavy DOM->string
