Problem

[ Problem ] When using Stream mode using Tool, it is printed normally in English, but languages such as Korean, etc.. are returned to Unicode. In the case of stream mode that is not using Tool, it outputs normally, but it seems like it is a bug to return to Unicode numbers when it is Tool. [ I Want ] I want to receive the result value parsed like normal Stream mode, not Unicode, even in Tool Stream mode. [ English Tool Stream Mode ] [code block] [ Response ] [code block] [ Korean Tool Stream Mode ] [code block] [ Response ] [code block] [ Korean Non-Tool Stream Mode ] [code block] [ Response ] [code block]

Fix Unicode Output in Tool Stream Mode

Medium Risk

The Tool Stream mode is not handling character encoding properly for non-Latin scripts, such as Korean. This results in the output being returned as Unicode escape sequences instead of the intended characters. The encoding mismatch occurs during the serialization of the response, where the output is not being correctly converted to UTF-8 encoding.

Awaiting Verification

Be the first to verify this fix

  1. 1

    Update Encoding Settings

    Ensure that the Tool Stream mode is configured to use UTF-8 encoding for output. This can typically be done in the configuration settings of the API or tool being used.

    javascript
    config.set('outputEncoding', 'UTF-8');
  2. 2

    Modify Response Serialization

    Check the serialization method used for the response in Tool Stream mode. Ensure that it properly encodes the output using UTF-8 instead of defaulting to Unicode escape sequences.

    javascript
    response = JSON.stringify(data, null, 2);
  3. 3

    Test with Multiple Languages

    After making the changes, run tests with various languages, including Korean, to ensure that the output is displayed correctly in Tool Stream mode. Validate that the output matches the expected characters.

    javascript
    console.log(response); // Check output for Korean characters
  4. 4

    Review API Documentation

    Consult the API documentation for any additional settings or parameters that may affect character encoding in Tool Stream mode. Ensure that all relevant configurations are applied.

  5. 5

    Deploy Changes

    Once validated, deploy the changes to the production environment. Monitor the output for any further issues related to character encoding.

Validation

To confirm the fix worked, test the Tool Stream mode with Korean and other non-Latin scripts. The output should display the characters correctly instead of Unicode escape sequences. Additionally, check the logs for any encoding errors during serialization.
