correctly encoded query string has been altered after decode and re-encode process

https://github.com/ktorio/ktor/blob/7092c30706f34242419a5f0c81445dca06461dc3/ktor-http/src/io/ktor/http/URLUtils.kt#L28

should the query string from URI be considered encoded already and skip the decode and re-encode process?

Start in ktor-http/src/io/ktor/http/URLUtils.kt at the linked line and trace how the URI query is decoded and re-encoded. Reproduce the reported alteration with an already encoded query, determine the expected preservation behavior, and verify it with relevant URL handling coverage if available.
