Hi,

I am generating epub3 from latex source.<= /div>
I was wondering why footnotes show a backlink to the original tex= t when I display the document in calibre, and why they do not when I displa= y the document on a kobo reader...

... until I fou= nd the backlink is indeed well present. It is "just" not displaye= d by kobo because the character set (by pandoc, I think) has no rendering o= n their font.

The backlink character, copied and p= asted from the .epub document itself, seems to be "=E2=86=A9=EF=B8=8E&= quot;.

I see two possible tricks here so that the = link will appear on kobo :
1. Change the character to another one= that would be rendered by kobo.
2. Change the default font of th= e document to one that has rendering for that character.

I have tried all available fonts on my device. There are actually th= ree classes of them.
(Listing them all below, this might be of in= terest to somebody in the future)

Avenir Next ; Ge= orgia ; Kobo Nickel : these fonts render absolutely nothing for that charac= ter, leading the human to believe the backlink does not exist. It is presen= t, clickable, just not rendered.

Amasis ; Caecilia= ; Gill Sans ; Malabar ; OpenDislexic : these fonts render "__" f= or that character. I find it "better" than the first family, but = still not great. It is not obvious for a non-tehnical human that this is a = backlink to the text.

AR UDJingxihei ; Kobo UD Kak= ugo ; Kobo Tsukishi Mincho : display oriental character (I think this is ch= inese / japanese depending on font) for the backlink character.
<= br>

Therefore, I tend to favor the first solution.= Do you guys know of a way to customize the "backlink =E2=86=A9=EF=B8= =8E" character set by pandoc in epub ?
Or is there a third a= pproach ?

Thanks,
