It's a SQL thing... it's about storing in Unicode specifically, not just UTF-8.

I don't know about other SQL servers, but MSSQL stores things in UCS-2, not UTF-8, so if you want more character support you're looking at nvarchar. I guess it could be varbinary too if you didn't mind making the app figure it out that way, but whatever.

Where I always get into trouble with nvarchar is when doing things with static strings, I always seem to forget to use N'string goes here' and use just 'string goes here' without the N, but that's typically also when there's a cast to varbinary in the mix as well.

e.g. cast('string' to varbinary(30)) != cast(N'string' to varbinary(30))
