Create a function App with Application Insight configured.
Create an http triggerd function and add the following code to the function.

 for(int i = 0; i < 200; i++){
      log.LogInformation("会員コード, ステータス");
   }

Execute the function
Open the associated Application Insight resource-> Logs ->Traces
Go through all the rows to find unexpected characters in the Trace as seen in the screenshot below.

It only happens on some of the traces? @cijothomas / @lmolkova -- any ideas here?

This is caused by ApplicationInsights ingestion issue and not specific to Functions or ApplicationInsights SDK. Ingestion team is looking into this, but there is no public-facing issue to track the progress.
