0 - 1 of 1 tags for ascii values incorrect

I have just complete some testing with a application I have made using the JDBC teradata driver. However, when I read from my resultset it appears that I lose non standard characters such as (± ¼ »). These are typically used within xml which is what I am also retrieving from the database, and they return as question marks, with an int value of 65533.
The values themselves are correctly shown in Teradata SQL assistant.
I have also tried creating a mysql database, which I could return the same characters from successfully.
