When I press the Space and Enter key to input the Chinese character, the application crashed. It is normal when I input english character.

Thanks for the report!

Reproducible in 1.2.1.

the application crashed.

In the todoapp-lite example, application itself doesn't crash (on my machine), we only see the crash in the logs.

We still can type Chinese text, but the popup is wrongly positioned.

Investigating further...

Cannot read field "x" because "rc" is null

Because of I have set the UncaughtExceptionHandler for my application and exit the application while it catched.

---

Main.kt
fun App() {

MaterialTheme {
    val content = mutableStateOf("")
    TextField(
        value = content.value,
        onValueChange = {
            content.value = it
        }
    )
}

}

fun main() = application {

Thread.setDefaultUncaughtExceptionHandler(UncaughtExceptionHandler())

Window(onCloseRequest = ::exitApplication) {
    App()
}

}

---

UncaughtExceptionHandler.kt
class UncaughtExceptionHandler: Thread.UncaughtExceptionHandler {
override fun uncaughtException(t: Thread?, e: Throwable?) {

    // Some operation for saving the crash log

    // Exit the application
    exitProcess(0)
}

}

So there are some bugs of TextFiled while inputing Chinese charcter
