youtube-dl print "_" as title

[Polliog]

Hi i'm creating a discord music bot and when the bot print the title of the song it print
"_" i have already tested so print all the dict and the result is "title: _" how can i fix this problem?

class Song:
    __slots__ = ('source', 'requester')

    def __init__(self, source: YTDLSource):
        self.source = source
        self.requester = source.requester

    def create_embed(self):
        embed = (discord.Embed(title='In riproduzione:',
                               description='```css\n{0.source.title}\n```'.format(self),
                               color=discord.Color.orange())
                 .add_field(name='Durata', value=self.source.duration)
                 .add_field(name='Richiesta da', value=self.requester.mention)
                 .add_field(name='Caricata da', value='[{0.source.uploader}]({0.source.uploader_url})'.format(self))
                 .add_field(name='URL', value='[Click]({0.source.url})'.format(self))
                 .set_thumbnail(url=self.source.thumbnail))

dict of the source:

{....... 'title': '_', ........
