Upside Down 7
ㄥ is a Bopomofo letter that matches a 7 rotated by half a turn.
The digit 7 is a flat top bar with a diagonal leg. Rotate it and the bar sits at the bottom with a vertical stroke on the left, close to an L shape. The Bopomofo letter ㄥ (U+3125) has that outline and is the character the flip generator uses. Bopomofo is a phonetic script for Mandarin, so devices set up for Chinese normally include a font for it.
