We already do this in Android (using a regex).

@Dbrant, I just verified this on Android and you are absolutely right. Removing Android App from this.
Thanks!

@BGerstle - can you attach one more screenshot where the sentence has a reference superscript?
The first sentence in Madame Clinton's article has no superscripts.

Sorry to be a prude :(

@Vibhabamba sorry I posted that screenshot on the wrong ticket. You should be able to verify this and the other share a fact bug in today's alpha build (should be 107). Ping me when you get in if you need more info.

@BGerstle Ideally it doesn't matter what I select - I should not see numbers in the card.
It mostly works unless I really mess with it, which is possible for users.
Text selection is always jumpy, never accurate.

See if you can handle case 2 (Screenshot from the time article).
Just mess around with what you select in lead section.

@Bgerstle based on the other 3 screenshots, 99% of the times, i don't see superscripts.
This is signed off by design.

Re-checked the samples given by @Vibha - no superscripts are displayed in 4.3.1(109). However, I filed T98626
4.1.3(109) Cannot use a custom text selection in 'Share fact' - could be related to the fix?
