I’ve built a deck of cards with LaTeX symbols I want to memorize, the symbols are used in the “Temporal Logic of Actions” or “TLA+” software specification language. On each card’s front I display some LaTeX symbol, for example the Greek capital letter Phi:
I accomplish this by entering a LaTeX snippet into one of my card’s fields:
This works well on Anki Desktop, but on mobile it looks like a black card with a gray square where the Phi symbol should be.
On the web, the symbol appears as a “broken image” icon.
Most LaTeX symbols in my deck do work correctly on all platforms! It seems unpredictable which will work and which won’t. For example, the “much less than” symbol works correctly with this LaTeX source:
That renders correctly on all platforms. However, this “much greater than” symbol only works on Anki Desktop:
