Probably the easiest is to start gnome-character-map/gcharmap; select "Ubuntu", search to U+25D2 and then *right-click* on the glyph. This will then show a larger rendering of the glyph and state the _actual_ font that the glyph is coming from in the pop-up.
Depending on whether it's correct or not you can go through the list of other fonts and see which ones are swapped.
