- The `dontEscape` parameter controls whether reserved characters are translated into escape sequences. This parameter should be set to `true` only if you are certain that all reserved characters in the URI have been escaped. Setting the value to `true` for a URI that has not been completely escaped can cause unexpected behavior. It is strongly recommended that you always set this parameter to `false`.
