Yeah, I think I was misunderstood.
I am also against swiss knife (I call these tools Office Syndrome), but ironically I still have a computer with NT4 but the last SP6 not 2.
Anyway, my idea was that
it would have been nice for Calibre to provide a workaround for the book embedding fonts that exhibit this behaviour, not only for its own skin. In the end, such fonts existed backthen (I use
Gabriola "for decades" and I don't have issues on my Sonies) and also ereaders based on webkit. It's not my problem, I admit, it's just a discomfort to see the preview in a strange manner - to see it correctly I have either to convert it to PDF or to sideload it onto one of my Sonies. God, I am lazy

, I am not really the adept of
Per aspera ad astra if I can do it otherways.
