Aura HD Superscripts rendered as subscripts

Nick Payne · 12-29-2014, 02:11 AM

I'm reading a book ("The Strangest Man", a biography of the physicist Paul Dirac, by Graham Farmelo, well worth reading) that contains quite a number of superscripted numbers. However, these are displaying as subscripts.

When I load the book into the ebook viewer built into Calibre, or open it in Sigil, the superscripts display correctly, but on the screen of my Aura HD (firmware 3.12) they come out as subscripts. If I look at the code in Sigil, it looks correct to me - eg 10<sup>78</sup> for ten to the power of 78.

I've tried several of the different fonts provided with the Kobo (Georgia, Malabar, Amasis), and the display of the superscripts is wrong with all of them.

I've checked an epub and a sideloaded kepub (not converted by Calibre, just renamed as .kepub.epub) on my Glo with firmware 3.12.0, and superscripts seem to be working correctly. Is your book a kepub or epub? Have you checked the stylesheet to see if <sup> has been redefined?

The books are epubs in the Calibre library but I'm using the KoboTouchExtended plugin to send them to the Auda HD as kepubs, as I prefer the kepub page numbering options.

No mention of <sup> in the stylesheet. In any case, had it been redefined, that would also affect the display of superscripts in Calibre or Sigil, and they look quite correct there.

I noticed something similar in the Hyperion books. Superscripts were smaller font size, but were barely elevated at all. It looked worse the larger the font size. It looked normal in Sigil and Calibre.

I found this in the css and changed it to 0.4em. Now it looks normal at any font size. Or you could just remove this section, and sup will work as the normal default height.

sup
{
vertical-align: 4px;
}

I'm reading on an Aura HD, and I think the high dpi makes any sizing by pixel count too small to be noticed.

Modern devices with such high resolutions should have an user-adjustable dpi setting, so that the the sizes of images and "pixels" can be modified, not just the font size. (The "should" above is only wishful thinking, I'm afraid.)
