What is your question or problem? Please describe.
When you look at the outputs of unicode strings in notebooks e.g. here https://pathway.com/developers/user-guide/connect/json_type, you will see that some unicode characters get printed directly if they go through an explicit .str conversion (like "Ł", unicode 0141, which is printed as a character), while some get escaped (like "ł" which is printed as "\u0142").
Describe what you would like to happen
I'm curious to learn if this is documented somewhere, and what is the intended behavior.
