Notion API unreadable dictionary keys

Question

I am getting the following properties dictionary:

value: {
          id: 'e44ddbba-580a-42af-882c-****',
          version: 70,
          type: 'page',
          properties: {
            '==~K': [ [ 'Yes' ] ],
            '=bhc': [ [ 'Yes' ] ],
            'BN]P': [ [ 'OSS,Node.js' ] ],
            'PO@I': [
              [
                '‣',
                [ [ 'd', { type: 'date', start_date: '2022-12-30' } ] ]
              ]
            ],
            'Yy:}': [
              [
                'e420f665-61de-474e-8804-****-profile_image-300x300.png',
                [
                  [
                    'a',
                    'https://s3-us-west-2.amazonaws.com/secure.notion-static.com/495afc3e-4d4b-48e8-*****/e420f6-300x300.png'
                  ]
                ]
              ]
            ],
            'a<ql': [
              [
                '‣',
                [ [ 'd', { type: 'date', start_date: '2018-03-07' } ] ]
              ]
            ],
            '}nqi': [
              [
                'sdcsbdciusc',
                [ [ 'a', 'sdckbsidcsidc' ] ]
              ]
            ],
            '~]S<': [
              [
                'The best techniques'
              ]
            ],
            title: [ [ 'Example article' ] ]
          },
          content: [
            '9420af59-f255-4387-8d35-97*****',

How am I supposed to decode those keys?

I need to get the all properties of the page. I am just using fetch Api.

This stackoverflow does not let me post unless I add this text.
