Given that each operating system comes with a different set of
collations, it seems unlikely you could even find two collations on
different OSes that even correspond. There's not a lot of
standardisation here (well, except for the unicode collation
algorithm, but that doesn't help with language variations).

I don't think this is a big deal for now, perhaps after per-column
collation is implemented we can work on the portability issues. Make it
work, then make it better.
