AZW3 (KF8) and embedded fonts

First off... this is no big deal. Everything displays/works as expected in the calibre viewer, kindle devices, and KindePreviewer ... but I've noticed something odd about converting ePubs with embedded fonts to the new MOBI format. Just wondering if it's the intended behavior or something I'm doing wrong/not understanding.

Starting with an ePub that contains unobfuscated, embedded fonts ... when you use calibre to convert to A) an AZW3 or B) a "new" mobi; the fonts seem to be obfuscated when using MobiUnpack to inspect the contents of the calibre produced file.

However when converting that same ePub (with unobfuscated, embedded fonts) to mobi using the "both" mobi output option (combination mobi/KF8) the fonts are un-obfuscated when inspecting the calibre produced file with MobiUnpack.

To recap: all fonts seem to end up obfuscated in the stand-alone KF8 conversions (AZW3 or the "new" mobi output option), but they end up un-obfuscated when converting using the "both" mobi output option (starting with the same ePub with un-obfuscated, embedded fonts).

Sorry if that makes no sense, as I said, it's curiosity more than anything.
