flet run --android failing

Description

When I run the command flet run --android I receive the next error:

Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\threading.py", line 1016, in _bootstrap_inner

UnicodeEncodeError: 'charmap' codec can't encode character '\u2588' in position 0: character maps to <undefined>

Code example to reproduce the issue:

import flet


def main(page: flet.Page) -> None:
    page.title = "NavigationBar Example"
    page.navigation_bar = flet.NavigationBar(
        destinations=[
            flet.NavigationDestination(
                icon=flet.icons.EXPLORE_OUTLINED,
                selected_icon=flet.icons.EXPLORE,
                label="Terrarium"
            ),
            flet.NavigationDestination(
                icon=flet.icons.SETTINGS_OUTLINED,
                selected_icon=flet.icons.SETTINGS,
                label="Settings"
            ),
            flet.NavigationDestination(
                icon=flet.icons.CAMERA_ALT_OUTLINED,
                selected_icon=flet.icons.CAMERA_ALT,
                label="View Camera"
            ) 
        ]
    )
    page.add(flet.Text("Temporal body"))

flet.app(target=main)

Describe the results you expected:

I want the QR code generated by this to use it in my andriod cellphone to use the qr code with flet app

Additional information you deem important (e.g. issue happens only occasionally):

It happens all the time when I use the command flet run --android, for normal use cases running it like python main.py it works fine, only with flet run --android I receive errors

Flet version (pip show flet):

0.19.0

Give your requirements.txt file (don't pip freeze, instead give direct packages):

flet==0.19.0

Operating system:

Windows

Additional environment details: NA

Apparently is a bug related to git bash, if you use gitbash in windows and you try to run that command there it fails, but if you open a powershell then you're able to run the command successfully. something weird but not sure if that can be considered a bug or just that should be added to the documentation as a NOTE?
