::after pseudo-element, a drop down arrow, not displaying on Android

Question

I have the following markup + CSS which works fine on all desktop browsers, and even sort of okay in Firefox on Android, but the ::after content doesn't render in Chrome (or the "default" browser) on Android.

Any ideas why this might be?

Chrome 42.0.2311 Android 4.4.3 (HTC One M7)

It seems like older versions of Android are having trouble to display \25BE on Chrome, it sounds like a bug. As a workaround you could change it to \25BC (similar shape) it then shows up correctly. Alternatively, you could also use font icons.

.u25BE::after {
    content: "\25BE"; 
}
.u25BC::after {
    content: "\25BC"; 
}

<div class="u25BE">25BE</div>
<div class="u25BC">25BC</div>
