I know this is not possible but this shows the effect I'm going for:

select cast(columnname as utf-8) from tablename

I have some greek language I need to encode and decode, specifically in a select statement as above.

Suggestions?

nope...data is manipulated by applications we have no control over. nvarchar won't work here, although normally it would.

Basically...I need to change the collation of the column alone when selecting. That might be a better phrasing.

Have you tried the COLLATE clause? BOL link: ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/tsqlref9/html/76763ac8-3e0d-4bbb-aa53-f5e7da021daa.htm

I think the only option you have to be able to store UTF-8 is to use VARBINARY. But, I'm not an expert in that arena.

For Tara's edification NVARCHAR is UCS2 not UTF-8, so data loss can occur if you have actual UTF-8 encoded strings. At least, that's my understanding.
