@MikeEL@mastodon.social Yes, and it was a surprise it was so sensitive to article body text. I did not dive deeper into it; if the reader should ignore such errors or not, how other RSS-readers manage it, if I added a new article for the feed - would that restart it or would the feed be lost for ever until the character was deleted, or if I had used other settings eg not download completely article in the feed, etc.
