IP2017 - Problem REST Encoding Latin chars

Hi Team,

We have a new projet from the scratch with IP2017. We are facing some problems using REST API with json:

1. When whe insert a account with a name with chars Latin, in DB the name add a different encoding. Example: REST Name:"Simões", in DB: "Simões" . When we query by account in REST information return is correct, but in Siebel client we saw the same thing that was in DB.

2. If we create a account with the name "João" in Siebel Client, in DB the Name is correct, but if we query using REST API the name is return different -> "Jo\ufffdo"
