[XeTeX] potential new feature: \XeTeXgenerateactualtext

[Adam Twardoch (List)]

Jonathan, 

is there any method in XeTeX to explicitly emit "ActualText" or override the automatic content generated by the new option? 

Or could you envision such a method? How would one need to approach it? 

(I'm not saying you should try implement it right away). :)
