nginx. How to replace spaces with "+" in the parameter string?

Question

linux

Good day to all!
The essence of the problem is this, there is a url:
example.com/some_text_1/some_text_2?param1=val1 param2=val2 param3=val3
But to get:
example.com/some_text_1/some_text_2?param1=val1+pa...
Or:
example.com/some_text_1 /some_text_2?param1=val1%20... I
thought to solve this issue using rewrite, but it does not process arguments, I found in the docks that there is a variable that stores a string with arguments - $args. But I can’t think of / find what to do to put down “+” or “% 20” instead of spaces.
Perhaps there is already a solution?
