(@aws-cdk/aws-events-targets module): Falsely detect change to Chinese text string

[tamakisquare]

CDK CLI falsely detects a change to Chinese characters when there's no change at all.

The Chinese characters are passed into the constructor of Lambda function invoking event rule target as the event object.

Reproduction Steps

new Rule(this, 'MonthlyReminder', {
  enabled: true,
  schedule: Schedule.cron({ day: '1', hour: '0', minute: '0' }),
  targets: [
    new LambdaFunction(sendReminderFn, {
      event: RuleTargetInput.fromObject({ message: '今日五號，請交月報。' }),
    }),
  ],
});

What did you expect to happen?

CDK CLI should know there's no change.

What actually happened?

CDK CLI falsely recognizes there's a change to the Chinese text string. Somehow, CDK CLI shows the current version of the text as a series of question marks "????".

Environment

• CDK CLI Version : 1.93
• Framework Version: 1.93
• Node.js Version: 14.6
• OS : MacOS 10.15.7
• Language (Version): TypeScript (4.1.2)

Unfortunately this is a bug in CloudFormation, and the CDK cannot do anything about this.

I've created an issue for you in their public bug tracker: aws-cloudformation/cloudformation-coverage-roadmap#814

Please go upvote that there, or ask your AWS support contact to escalate the issue internally.
