Here my analysis
The problem is due to the method
org.apache.sling.engine.impl.parameters.ParameterSupport.getRequestParameterMapInternal()
that call the Util.fixEncoding(parameters);
Before calling that method all the values are OK but after they are encoded in
ISO-8859-1. To fix the problem I send an other parameter _charset_=utf-8. But I
think that is the wrong way to do it.
