Hello,

I am reading some mathematic books on Kobo Libra Colour.

While the matrices are displayed correctly in Calibre viewer, they appear as "single line" on Kobo reader. Here is an example:

Original matrix:
[ 1 2
2 0
3 1]

Would appear on Kobo as [122031], with no space/newline,...
Making it impossible to interpret...

I tried with ePub or KePub, no difference.

Is there anything I could try to fix that?

Thanks in advance for your ideas.
