Describe the bug

As a result of the request, I get an empty response (error code 200). At the same time, if I make a request to this address without the last two characters "%f2%f0" ("тр" in Russian in Win-1251 encoding), then the correct data is received in response.
Previously, I used an almost identical configuration in rest requests and everything worked as it should. Therefore, I assume that these two characters are the reason for the empty response. Unfortunately, to refuse them means to receive incorrect data.
This query also returns data if you use it in the browser or in the curl command.
I have tried many ways to write this query, but I did not get the answer I needed.

Isn't the problem that the response contains a header: Content-Type: application/x-javascript; charset=utf-8, while it is not utf-8? Also my browser shows it like:

As far as I understand, no. For example, the following request returns correct data:

- resource: https://mu-kgt.ru/informing/wap/marsh/?action=getMarshData&m=9
  name: Автобус 9
  scan_interval: 120
  parser: lxml
  # log_response: true
  sensor:
    - unique_id: 2a4b318e-a4b2-4216-b9ec-5f7e1d302301
      name: Автобус 9 (ост. Сибтяжмаш)
      icon: mdi:clock
      value_template: >-
        {%- if 'ts_line' in value_json -%}
          {%- set stops = value_json.ts_line.A -%}
          {%- for stop in stops -%}
            {%- if stop.st_regnum == 333 -%} {{ stop.st_arrive }} {%- endif -%}
          {%- endfor -%}
        {%- endif -%}
      on_error:
        log: warning
        value: none

For the sake of interest, I tried another request:

- resource: https://mu-kgt.ru/informing/wap/marsh/?action=getMarshData&m=5%f2
  name: Троллейбус 5 (тест)
  scan_interval: 120
  parser: lxml
  log_response: true
  sensor:
    - unique_id: 9791c6fb-f047-4d8a-8bcf-a11242d4888f
      name: Троллейбус 5 (Test)
      value_template: >-
        {%- if 'ts_line' in value_json -%}
          {%- set stops = value_json.ts_line.A -%}
          {%- for stop in stops -%}
            {%- if stop.st_regnum == 550 -%} {{ stop.st_arrive }} {%- endif -%}
          {%- endfor -%}
        {%- endif -%}
      on_error:
        log: warning
        value: none

And I get an empty response. The difference in requests is apparently only in these two symbols in the link (denoting different types of transport)
