Web Deployment Task Failed: Unicode keyword not suported

I'm now trying to build deployment package for my Visual Studio 2010 ASP.NET Project. But, I'm getting an error that I cannot resolve:

Error   1   Web deployment task failed.(Object of type 'dbFullSql' and path 'Data Source=localhost;Persist Security Info=True;User ID=aba1437;Password=aba1437eg;Unicode=True' cannot be created.)

Object of type 'dbFullSql' and path 'Data Source=localhost;Persist Security Info=True;User ID=aba1437;Password=aba1437eg;Unicode=True' cannot be created.
The value 'Data Source=localhost;Persist Security Info=True;User ID=aba1437;Password=aba1437eg;Unicode=True' is not a valid connection string or an absolute path.
Keyword not supported: 'unicode'.       0   0   Titanic

The connection string looks in the following way:

Data Source=localhost;Persist Security Info=True;User ID=aba1437;Password=***********;Unicode=True

I would really appreciate any suggestions because I did not found any useful tips to resolve the problem. Thank you!
