after researching casperjs modules solution found ! the issue due to base64encode of data in addition to handling binary data

Workaround till fix: I removed the encoding function and modified open file flag for wb to w

OLD casper.js 

fs.write(targetPath, cu.decode(this.base64encode(url, method, data)), 'wb');

New casper.js 

fs.write(targetPath, this.base64encode(url, method, data), 'w');

OLD clientutils.js

return this.encode(this.getBinary(url, method, data));

New clientutils.js

return this.getBinary(url, method, data);

This appears to be a PhantomJS bug. (I just upgraded from 1.9.0 to 1.9.2 to be sure: I'd hoped this bug report might have meant it was fixed in 1.9.1.)

However it does work with SlimerJS. When I run with:

casperjs --engine=slimerjs test.js

I get a 356 byte file, exactly as I do with wget (and it displays as UTF-8, correctly). With PhantomJS as the CasperJS engine I get a 177 byte file, that does not display anything useful.
