If a paper cites a work and its translation, is it counted as two citations for calculating h-index? If a bibliography mentions a work two times, once in its original and once in its translation, how does this count in the author's H-index?

E.G.: 


Everyman, J. (2000), A work on citations, Cambridge. 
Everyman, J. (2001), Un lavoro sulle citazioni, Roma.


The (2) is the italian translation of the (1). 
This means that the author gets 2 citations, but they actually refer to only 1 work. How does this affect citation count and metrics?
The h-index, as usually employed, does not take translations into account. The case you cite would be effectively the same as citing two genuinely different publications by the same author. Under certain circumstances, this might increase you h-index by 1. I leave it to you to decide whether this is fair or not.
