The .svg from a.m. URL contains a "small type Phi", which will be replaced by a "capital type Phi" in the replacement .png, which is created for using the image in WIKIPEDIA articles. Steps tor reproduce: 1. open a.m. URL you will see the (wrong) "Φ" for the angle 2. click 'Elevation_angle_0.svg' The .svg image will be shown in your browser (if it is able to show .svg images) with the correct letter "φ".
I also have a problem of this kind, where a Δ is replaced by a "D" in the PNG version, compare http://commons.wikimedia.org/wiki/Image:Ellingham-Richardson.svg and http://upload.wikimedia.org/wikipedia/commons/c/c3/Ellingham-Richardson.svg there is also a problem with the arrow heads
For the problem with arrows, see bug 5325.
Concerning the \Delta, I'll change the D in Symbol by the unicode character, which may solve the problem.
I've changed the D in symbol font by the unicode character Δ, and it did not solve the problem: the delta does not appear at all in PNG rendering.
Could this be related to bug 8666?
Both test cases appear to be fixed now, after installing more fonts. The problem with the arrows is unrelated to the original report.
