+// The following 2 Glyphicons are omitted for the time being because
+// they currently use Unicode codepoints that are outside the
+// Basic Multilingual Plane (BMP). Older buggy versions of WebKit can't handle
+// non-BMP codepoints in CSS string escapes, and thus can't display these two icons.
+// Notably, the bug affects some older versions of the Android Browser.
