GWT Textbox Encoding and RPC

Question

Let's say I have a TextBox and the user puts some data in it. I then send the data over RPC, with something like this (synchronous version of interface)

public void submitText(String userData) {
  dao.saveText(userData);
}

My questions are:

• What is the encoding of the userData? This is a trick question, since Strings in java are stored in UTF-16, what I want to know is if my text box sends funny characters like ã or Í or €, and if I later feed that chars to a xml document, what should be the xml encoding?
• Do I need to care about encoding when submitting data this way? Or GWT assures me that the chars within the userData are properly converted from the http request?

Answer 1

2 issues:

1. The "Serialization" or "Marshalling" of data built into RPC handles binary conversions such as machine byte order differences.
2. the "xml document" you refer to should use "UTF-16" encoding if you plan on writing Java Strings as "binary characters" to it.
3. another approach is to use 8-bit encoding and translate all the 16-bit characters to markup as in non-breaking-space "
