Data Migration from Sybase 15 with ? instead of char.

We are Migrating from Sybase 15 to SQL Server 2008, the Sybase server is using us_english and iso_1 and we are using SSMA to Sybase  5.2 to do the migration, the connection string we are using is this:Server=XX;Port=XX;uid=XX;pwd=XX;language=us_english;charset=iso_1;

We have columns with these chars “ ’ ”, running ascii in the Sybase server I got these values back 174,146,148, after migrating the data the chars get converted to ?.

Is there a way to get the conversion right?, the collation in the SQL server is SQL_Latin1_General_CP1_CS_AS, do I need to change it to another one?

Thanks.
