How do you encode a string as an destination argument for `NavHostController.navigate()`? My database is backed by a `String` primary key that can contain chars like `?` and `/`.

Navigation will automatically decode for you though

Is it fine to use this even if my key does not confirm to the `Uri` standard?

edit: nvm it is the static method that takes a `String`

Reviving this thread: If I encode "Nick Achtien (age 4)", then get the item from the back stack, it comes back as "Nick+Achtien+(age+4)" .  I'm encoding because I want to make sure that this text doesn't contain any characters like "/"

Navigation will automatically `Uri.decode` the string values before putting them in your `arguments`. It sounds like something is causing you to double encode

```    object LabResultsList : HistoryRoutes("labresults/{patientId}/{patientTitle}/{isDependent}") {
        fun createRoute(patientTitle: String, isDependent: Boolean, patientId: String): String {
            val encodedPatientId = patientId.encode()
            val encodedPatientTitle = patientTitle.encode()

            return "labresults/$encodedPatientId/$encodedPatientTitle/$isDependent"
        }
    }

composable(route = HistoryRoutes.LabResultsList.route) { backStackEntry -&gt;
    val patientTitle = backStackEntry.arguments?.getString("patientTitle")!!
    val patientId = backStackEntry.arguments?.getString("patientId")!!
    val isDependent = backStackEntry.arguments?.getBoolean("isDependent")!!
    LabResultsListScreen(
        navController = navController,
        patientId = patientId,
        patientTitle = patientTitle,
        isDependent = isDependent
    )
}

private fun String.encode() = URLEncoder.encode(this, UTF_8.name())```


oh maybe it's because i'm using URLEncoder?

Don't use `URLEncoder`, you have to use `Uri.encode`
