Hubiera used for "should have"

[tacuba]

I'm reading a book that deals with Spanish verb usage and the author is from Spain. There is a chapter dealing with modal verbs in Spanish, and not once does he mention that "hubiera" can be used for "should have." He gives dozens of examples using "deber" or "haber debido", but not "hubiera."

Is "hubiera" used as "should have" a Latin American usage? And if it is, do speakers from Spain understand the form?

Thanks
