Aura Supported Unicode ranges

kuvera · 06-11-2015, 02:10 PM

Hi, I'm considering buying an Aura SD.
Please let me know if it supports any glyph from a font that is embedded into Epub files. More specifically Unicode character range "Latin Extended Additional" (0x1Enn) (latin transliteration for Sanskrit and Vietnamese letters). I need confirmation because latest Nook shows squares even if I supply the font with the book and set publisher defaults.
It would be nice to know if the factory fonts have those glyphs, or if I install my own, will any character show up with fonts not embedded in the book? But it's not crucial if embedded fonts work fine.

The only built-in font with any glyphs from Latin Extended Additional is Kobo Nickel, it is not very complete, but it displays the glyphs it has. I have a few sideloaded fonts that have some of those glyphs and they display okay too.

If the font has the glyphs then I think they'll be displayed, it shouldn't matter whether the font is built-in, sideloaded to the device, or embedded in an epub.

Edit: Attached are screenshots from my Glo (fw 3.16.0) displaying an epub table of unicode characters U+1E00 - U+1EFF. On the left is the built-in Kobo Nickel font, and on the right a sideloaded TeX Gyre Bonum font:

Thank you very much, this is very helpful.
The built-in one is missing the glyphs that I need, but your sideloaded font has them displayed.

It means Glo does not suffer from the same flaw as the Nook Glowlight, and I can probably assume that Aura won't either.

You can sideload my Modified version of Charis SIL and you'll get the glyphs you need. Plus is looks very good on an eInk screen.
