<http://trac.webkit.org/browser/trunk/WebCore/platform/text/BidiResolver.h?rev=61921#L909> suggests that the reason embedding characters are omitted from the BidiRuns, and consequently from the InlineTextBoxes, is their effect on rendering complex text with ATSUI.

Perhaps this bug can be resolved with two localized changes and without touching so much code, by (1) removing the aforementioned BidiResolver code that omits over Unicode control characters from BidiRuns and (2) patching the ATSUI-based implementation of the ComplexTextRun constructor to check for a leading embedding character and remove it if necessary (analogously to how it adds embedding characters for implicit embedding).
