With the programme Sigil, I have created an epub that contains mathematical symbols, coded in html.
On my computer, all the mathematical symbols of the epub are correctly displayed.
On my Kobo Aura, however, four of them are not displayed correctly (they are all shown as a box):
∀ ∃ &and; &or;
Is that "normal", ie the Kobo Aura simply doesn't display these mathematical, html symbols?
(NB: It does display several other mathematical, html symbols coded in a similar fashion.)
Or could this be due to a bug in the program Sigil?
In all cases, is there a way to fix that?
- By changing the code used for these symbols?
- By tweaking my Kobo Aura? (I'd like to know; but this would not be useful if I want to share the document "with everyone".)
