Handicap symbols font

Classification: 

Need a font that contains the symbol of a man in a wheelchair (for wheelchair accessibility) and the symbol of an ear with small arcs (for listening devices for the hard of hearing available).

Comments

First one that came to mind but there should be more: Wayfinding Sans Symbols. First symbol here, second here.

The symbols aren't in boxes; OTOH, the font is free...
