Hi

Yes, these options come from settings in the Hyperref dialog.

"bookmarks=..." = "Generate bookmars (toc)"
"breaklinks=..." = "Break links over lines"
"pdfborder=..." = "No frames around links"
"colorlinks=..." = "Color links"
"backref=..." = "Backreferences"

However, there seems to be no option for the "unicode=..." which seems 
like an oversight. And the biggest problem is that according to the manual:

Note however that some options (for example unicode) can only be used as 
packge options,and not in \hypersetup as the option settings are 
processed as the package is read. (p. 6)

So, unicode=false has no effect as an additional option.

My guess is that this is a bug in LyX but others might know better.
