When to use it
ℵ writes U+2135 (Alef Symbol), a letter from the Unicode Letterlike Symbols block, encoded since Unicode 1.1. These characters exist mostly for compatibility with older character sets; for anything beyond simple cases, <sup>, <sub> or MathML give more control.
The name dates from HTML 4, so it works in every browser and in old email clients.
