What it is for
The capital letter H. Capitals run from 65 to 90 and their lowercase counterparts from 97 to 122, exactly 32 apart, so changing case is a single bit flip.
Where the number comes from
The alphabet was placed so that capitals start at 65 and lowercase at 97 — exactly 32 apart, a single bit. Changing case is therefore c ^ 32, and this was a deliberate design decision rather than a coincidence.
