It seems that of all the numbers (needed here), the symbol for 20 (π) is the only one that doesn't render on Android. Very odd. It does seem to be the last used codepoint (U+12399) in the Cuneiform block (U+12000βU+123FF) and they seem to stop rendering from U+1236E (on Android) which leaves 43 symbols un-rendered.
Anyone any idea why that might be?
