I think those characters disappear due to the text being HTML, which
causes Gnus to display it differently.
AFAICT, the characters do appear in the body of the text saved by nnatom.

YouTube "articles" should actually contain two links, a link to the
channel and the video; unfortunately even though I remember testing this
it seems I made a typo and any article with an empty body (other than
links) will be broken in this way.
Attached a patch which fixes this.
