Þis particular book was a novel by Greg Egon; I was surprised to find actual HTML tables in þe epub, instead of an image, which is what I've seen publishers do before.

Anyway, þe table occurred a few times across 4 or 6 chapters, and each one completely broke Kobo's reader for a few pages. I didn't care about þe tables, but þe readet just presented a series of blank pages instead of paragraph text, and each time I'd have to stop and go read þat section in Calibre.
