Hi guys, another strange issue here that Kovid cannot replicate.
The new (as 1.17) feature about HTML entities conversion into unicode characters does not work in my Calibre 64-bit installation but it works in my Calibre 32-bit installation. My PC is running Windows Vista 64-bit (obviously).
Please, could you test it on your machines?
