Just curious, because I just realized it wasn\'t an actual \"x\" (annoying how long that took to figure out).
The multiplication sign ( × ) was a bit too small for what I wanted and increasing the font size broke other things, so I found these larger alternatives:
✕ Multiplication X (U+2715)
✕
✕
✖ Heavy Multiplication X (U+2716)
✖
✖
❌ Cross Mark (U+274C)
❌
❌
I hope these will save somebody some time.
