Description

Expected Behavior

The list filter docs and visibility docs don't allude to any restrictions over what sorts of values are permitted in string filters, so my general expectation is I can throw anything at it.

For example, I should be able to do Keyword = 'foo-value' as well as Keyword = 'foo?-value'

Actual Behavior

When a filter string contains a question mark, the a context cancellation error is indicated on the client side, and the following error is logged by temporal:

Research direction

Start in samples-server/compose with docker-compose-postgres.yml and reproduce the failing ListWorkflowExecutions query using a value containing '?'. Trace the request into the PostgreSQL visibility query and inspect the error path referenced at common/rpc/interceptor/request_error_handler.go:96. Done means the same keyword filter succeeds with both 'foo-value' and 'foo?-value' instead of timing out.
