Symbol

 * 1) A cross potent.
 * 2) A crutch cross.

Usage notes
The name of this Unicode character is a misnomer. The glyph in the official Unicode character sheet is not a Jerusalem cross but a, having four arms of equal length ending in bars, each like a rotated capital.

The is a more complex symbol consisting of either a  or a cross potent surrounded by four small Greek crosses, one at each corner.
