mORMot Open Source

Greetings..
I am a big fan of this opensource project. I am a delphi student and came across a problem while trying to send get request using TWinHttp. The result is in rawbytestring which cannot show unicode characters.
The same result can be obtained using IdHttp.get() method, but it is very slow in comparison to TWinHttp. How can I get the unicode characters in the result. I am using Delphi XE6.
