Code example to reproduce the issue:

import flet as ft


def main(page: ft.Page):
    page.title = "One"
    page.theme_mode = ft.ThemeMode.LIGHT

    def nav_on_change(e: ft.control_event.ControlEvent):
        print("中文")
        match e.data:
            case "0":
                print("one")
            case "1":
                print("two")
            case "2":
                print("three")
            case _:
                print("other")

    page.navigation_bar = ft.NavigationBar(destinations=[
        ft.NavigationDestination(icon=ft.icons.EXPLORE, label="Explore"),
        ft.NavigationDestination(icon=ft.icons.COMMUTE, label="Commute"),
        ft.NavigationDestination(
            icon=ft.icons.BOOKMARK_BORDER,
            selected_icon=ft.icons.BOOKMARK,
            label="Explore",
        ),
    ], bgcolor=ft.colors.GREEN_50, elevation=1, label_behavior=ft.NavigationBarLabelBehavior.ALWAYS_HIDE,
        on_change=nav_on_change)
    page.add(
        ft.Text("Body"),
        ft.ElevatedButton(text="打印中文", on_click=lambda _: print("中文"))
    )


if __name__ == '__main__':
    ft.app(target=main)

As a workaround run with python directly, without flet run:

python main.py

@FeodorFitsner

I know this way, but I want to use the hot reload

Should be solved with this proposal: #863

[FeodorFitsner]

Could you please try encoding fix with pre-release version of Flet module:

pip install flet --upgrade --pre

and let me know if that worked. Thanks!
