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)
- Decimal HTML entity:
✕ - Hex HTML entity:
✕
✖ Heavy Multiplication X (U+2716)
- Decimal HTML entity:
✖ - Hex HTML entity:
✖
❌ Cross Mark (U+274C)
- Decimal HTML entity:
❌ - Hex HTML entity:
❌
I hope these will save somebody some time.
