Describe the bug

When using the OpenAI Agents SDK with tracing enabled, the exporter fails if any string (e.g., prompt or metadata) contains characters outside the Latin-1 (ISO-8859-1) range — such as Unicode curly quotes (“ or ”, code point 8220). This throws an internal TypeError in undici.

Debug information

• Agents SDK version: "@openai/agents": "^0.0.9",
• Runtime environment ( Node.js 22.16.0)
