How store the vector (Embedding) from .csv file in Indexes

I have a .csv file, which consist of 2 columns: Sentences (Thai Sentences) and Embedding (vector with length 1536) as follow:
I want to store the Embedding along with Thai sentences in Indexes. I’ve looked at examples of storing vectors and sentences from this example Hello, Pinecone!.
Then, I applied it to my problem. I got the error as follow:

ApiException: (400)
Reason: Bad Request
HTTP response headers: HTTPHeaderDict({'content-type': 'application/json', 'date': 'Fri, 28 Apr 2023 08:20:46 GMT', 'x-envoy-upstream-service-time': '0', 'content-length': '1251', 'server': 'envoy'})
HTTP response body: {"code":3,"message":"ID must be ASCII, but got อุตุฯ ประกาศฉบับ 5 เตือน 'พายุฤดูร้อน' ถล่ม 27 จังหวัด ","details":[]}

I’m not sure Is the problem caused by my sentence in Thai? If so, how can I fix this problem?
