Weird eclipse error when working with XSL. How to solve?

Question

I'm using XSL to transform a XML in HTML. I'm using Eclipse Java EE IDE for Web Developers (Version: Luna Service Release 1 (4.4.1) Build id: 20140925-1800). My OS is Windows 8.1 and I've installed JRE and JDK 1.8u25.

I've tried run it with a clean Eclipse installation, and I've installed the required plugins.

I'm sure that the files are UTF-8, actually with simple files it won't work ("helloworld" files).

But the most weird thing is that I've tried to run my workspace on Xubuntu VM with same version o Eclipse and JRE/JDK 1.8 and I've no errors.

I've searched for this error and none of the answers/tutorials worked.

When I run the XSL Transformation I have the following error:

Plug-in: org.eclipse.wst.xsl.launching
Severity: Error
Message:Invalid byte 2 of 3-byte UTF-8 sequence.

Answer 1

I've found the solution. In my case the problem was that my path includes my username that has accented characters. So I've solved the problem moving my Workspace to C:// or outside of my User area and it worked.
