UnicodeDecodeError

[DoctorChe]

Hi,

I'm trying to use Cyrillic in the interface, but app does not start. Here is the code:

main.py

#  -*- coding: utf-8 -*-

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen

class MainScreen(Screen):
    pass

class AnotherScreen(Screen):
    pass

class ScreenManagement(ScreenManager):
    pass

presentation = Builder.load_file("main.kv")

class MainApp(App):
    def build(self):
        return presentation

MainApp().run()

main.kv

#  -*- coding: utf-8 -*-

ScreenManagement:
    MainScreen:
    AnotherScreen:

<MainScreen>:
    name: 'main'

    Button:
        on_release: app.root.current = 'other'
        text: 'Другой экран'
        font_size: 50

<AnotherScreen>:
    name: 'other'

    Button:
        on_release: app.root.current = 'main'
        text: 'back to the home screen'
        font_size: 50

When I run the program on Android, I got:

[INFO ] [Logger ] Record log in /storage/emulated/0/Download/TrafficTaxApp/TrafficTaxApp/.kivy/logs/kivy_17-12-03_2.txt

UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 186: ordinal not in range(128)

On Ubuntu, everything is good.

Any idea on this?

I think there's a known issue with the kv decoding codec on Android, where it defaults to ascii rather than utf-8. A workaround is to remove the non-ascii characters from the kv code and set (or at least import) them from the python code.
