Render Some Persian Word have duplicated part

[AbolfazlAdhami]

I am using react-pdf for a project where we are issuing a series of documents and rulings in Farsi language and Persian font for officials and legal rulings for contractors of municipalities and rural districts, but we have a problem and that is when a city Or the village is made of a repeated part from its name, like Lala or Kelkol Sofeli, it only prints one part, which can be La or Kolkol Sofeli, how can it be solved?
