The page title in English show this:

> Episode 48 – The Seven Swans / The Mysterious Love Poem / 'O' Is Hard

Curiously the title of the page in Portuguese shows this:

> Episódio 48 – Os Sete Cisnes / O Misterioso Poema de Amor / "O" é difícil

As usually the subtitle file receives the name of the episode that in Portuguese presents a kind of code #("O") is running this conflict.

How can i fix this?

[OlaBrasil]

Thanks, Yan. But is it the problem? Cause the video is released to my country (Brazil) and I can usually watch it in Portuguese subtitles through the website. The problem only occurs when I try to download the subtitle using youtube-dl process.

I try use the Geo-Restriction commands but the error message still persists.

Anyway I managed to download the subtitle by another phyton process and I will use it in isolated cases like this. But I still prefer youtube-dl to download in batches.

The labal indicates this video is blocked in some countries (at least in Taiwan), so I can't check what's the actual cause yet.

Mind sharing what's the tool you're using? That should help on identifying the problem in youtube-dl.

[OlaBrasil]

Thanks again for returning the reply.
I can explain the process but just hope that not violating any community rule.

I'm using the Crunchy Xml Decoder
that convert/decrypt the Crunchyroll's XML episode subtitle to ASS.

Download HERE or HERE

I made a ilustration how to use HERE.

It's not actually in the subtitles itself, it's crashing before it even hits the part where it checks subtitles, it's still trying to pull video information in that crash, says line 417 in crunchyroll which is the video_description regex/json

415        video_description = self._parse_json(self._html_search_regex(
416            r'<script[^>]*>\s*.+?\[media_id=%s\].+?({.+?"description"\s*:.+?})\);' % video_id,
417            webpage, 'description', default='{}'), video_id).get('description')

Here's the line it's parsing

<script type="text/javascript">
 $('.collection-carousel-contents div[media_id=610541] .hover-bubble').data('bubble_data',{"name":"The Seven Swans \/ The Mysterious Love Poem \/ 'O' Is Hard","description":"A sister saves her brothers, a love is found, lost, and found again, and you put an \u201co\u201d in front of everything to be polite."});
   </script>

I'm guessing you're right in that it is having issues with the unescaped single quotes, but it's not actually due to trying to download subs
