vosk add-on does not start if a file with sentence templates is added.

HAOS 2024.2.5

The addon works without using templates. Only the language setting has been adjusted.

But if I add ru.yaml, then a cyclic error occurs at startup.

sentences:
  - включи[ть] {lght}
  - выключи[ть] {lght}
  - уровень диоксида углерода
  - (включи|установи|запусти)[ть] {preset} плейлист
  - (включи|установи|запусти)[ть] плейлист [номер] {preset}
lists:
  lght:
    values:
      - фонарь
      - квадрат
      - торшер
      - зеркало
      - дневной свет
      - луч
  preset:
    values:
      - in: (один|первый)

      - in: (три|третий)
        out: 3
      - in: (четыре|четвертый)

        out: 8
      - in: (девять|девятый)
        out: 9
      - in: (десять|десятый)
        out: 10

What could be the cause?

[synesthesiam]

It looks like the file encoding isn't quite right. The add-on expects the file to be UTF-8 encoded, but Windows will almost screw this up and use a different encoding. You may need something like Notepad++ to do this correctly.

Thanks for solving the problem. Indeed, windows notepad uses ANSI encoding according to the standard. But you can also choose utf-8. Now everything has started without any problems.
