I am using one xpcom object in my extension and the xpcom binary component is not loading if the windows username contains non ascii username. 
In my case the AppData parth is "C:\Users\മനു\AppData\".

In error console,
Components.classes["@mydomain.com/cloudsearchdownload;1"].name
returned

@mydomain.com/cloudsearchdownload;1


and this Components.classes["@mydomain.com/cloudsearchdownload;1"].createInstance()
returned
