Hi Hasan,
Thanks for getting in touch with us.
We are assuming you are not much familiar with coding or escaping characters.
Without getting into too many details, you do not need to worry about what you are seeing in the code. If you check your page in any testing tool, you will see that the letters are correctly encoded:
https://search.google.com/structured-data/testing-tool/u/0/
That means Google will see the correct letters.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
