Chinese will be garbled in function calling

[andyli0123]

Description of the bug:

1. If the result contains Chinese, Gemini reads it as garbled. (always)

response = await chat.sendMessage(Content.functionResponse(functionCall.name, result));

2. Properties will also be garbled. (sometimes)

Actual vs expected behavior:

\350\230\213\346\236\234 should be 蘋果
\351\200\231\345\200\213\346\274\217\346\264\236\345\245\275\345\232\264\351\207\215 should be 這個漏洞好嚴重

Any other information you'd like to share?

Simulates a garbled situation in Python:

encoded_string = "\350\230\213\346\236\234"
decoded_string = encoded_string.encode('latin1').decode('utf-8')
print(decoded_string)
