What steps will reproduce the problem?
1. open the index.html
2. in the source tab type

The Open Hardware or better the Free (as in freedom) Hardware is a part of the 
Free Culture and it is a movement that shares information about hardware 
components such as [http://en.wikipedia.org/wiki/Circuit_diagram circuits 
diagrams] or as in the last years the Hardware Description Language (HDL) code, 
[http://en.wikipedia.org/wiki/Bill_of_materials bill of materials] and 
[http://en.wikipedia.org/wiki/Printed_circuit_board printed circuit boards].

3. click on preview tab

What is the expected output? What do you see instead?
The output must be:
The Open Hardware or better the Free (as in freedom) Hardware is a part of the 
Free Culture and it is a movement that shares information about hardware 
components such as <a 
href="http://en.wikipedia.org/wiki/Circuit_diagram">circuits diagrams</a> or as 
in the last years the Hardware Description Language (HDL) code, <a 
href="http://en.wikipedia.org/wiki/Bill_of_materials">bill of materials</a> and 
<a href="http://en.wikipedia.org/wiki/Printed_circuit_board">printed circuit 
boards</a>.

The script generates this output instead:
The Open Hardware or better the Free (as in freedom) Hardware is a part of the 
Free Culture and it is a movement that shares information about hardware 
components such as <a 
href="http://en.wikipedia.org/wiki/Circuit_diagram">circuits diagrams] or as in 
the last years the Hardware Description Language (HDL) code,
