Not defaulting to UTF-8 encoding in request

[andidev]

After upgrading to Spring Boot 1.3.0.M5 from 1.2.6.RELEASE I have problems with logging in with usernames containing non ASCII characters. It seems that the encoding in the request parameters is ISO-8859-1 instead of UTF-8 and therefore the user is not found.

The login is trying to POST with

'Content-Type': 'application/x-www-form-urlencoded'

Here is a sample JHipster application showing this problem. You can start it with mvn spring-boot:run and try to login with username abcåäö and password user.

The issue can be solved with adding the encoding into the content type by setting it to

'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'

in src/main/webapp/scripts/components/auth/provider/auth.session.service.js

Here is a screenshot of the request from the browser console

and here is the request created by the server

as you can see the ecoding is not UTF-8 but the queryStringEncoding is UTF-8
