nginx servers return errors when special characters {}|\^ are present in query parameters

[kimjeongwonn]

When query parameters contain special characters like {}|^, some nginx servers return HTTP errors, making the application inaccessible. This issue occurs because these characters are not properly encoded according to RFC 3986 standards.

Proposed Solution

Add {}|^? to the list of characters encoded by the encodeQueryValue function to ensure RFC 3986 compliance and server compatibility.
I have already submitted a pull request #1068 that implements this fix. Please review and consider merging this change to address the nginx compatibility issues.

As answered in #1068 (comment), do you have a reproduction nginx setup that I could try to run tests against?
