Character Encoding in Generated Classes
Classes created by HydraExpress parse XML using class rwsf::XmlReader. An instance of rwsf::XmlReader converts XML source to UTF-8, regardless of the original encoding. For details on the encodings that the reader supports, see the entry for rwsf::XmlReader in the HydraExpress C++ API Reference Guide.
HydraExpress produces XML documents in UTF-8.
