UnicodeDecodeError: 'charmap' codec can't decode byte

[yuis-ice]

When I have the following urls.yaml, it succeeds,

kind: url
name: rakuten card promo
url: https://www.rakuten-card.co.jp/campaign/add-card/
filter: 
  - css: "section[id='rule_detail']"
  - html2text:
    method: re
  - grep: "2,000"

> urlwatch --urls urls.yaml --test-filter 1
                2枚目の楽天カードを作成＆利用特典…2,000ポイント（期間限定ポイント）

but with the following urls.yaml, where I have a utf-8 text content on it, it gets an error.

kind: url
name: rakuten card promo
url: https://www.rakuten-card.co.jp/campaign/add-card/
filter: 
  - css: "section[id='rule_detail']"
  - html2text:
    method: re
  - grep: "2,000ポイント"

> urlwatch --urls urls.yaml --test-filter 1
