squares instead of numbers in iBooks/iPad

robert! · 07-29-2010, 10:44 PM

I am trying to import a PDF into calibre to convert to my iPad..

however whenever I do this, I see squares instead of numbers...
I dont know what it could be, and I dont know how to resolve it...

I am not technical, so if you know the solution, please keep it simple!

thanks,

maybe take this over to the calibre forum as your problem is importing into calibre?

let me re-state my problem..

after I convert my PDF in Calibre and sync with iPad, I open it up as a book in the iPad and every character that should be a number is actually a square..

That's because your PDf liely uses a special math font to display the numbers. Conversion wont be able to handle that.

so there is no fix?

No, use an app that can read PDF on your device.

i can read PDF, but in iPad i cant highlight passages in PDF...

are there any other applications that would convert this PDF into a book?

There are lots of applications that convert PDF, whether any of them will be able to successfully convert this particular PDF, I can't say. Try a few. Just google PDF converters

iAnnotate PDF is available for iPad.

Probably the numbers are specialized figure representations (proportional/tabular old-style, proportional lining), and are wrongly encoded in the Private Use Area --- is the .pdf publicly available? What fonts/versions are being used?

(And why use that as a source? Can't you get an original file?).

by the way, Calibre is wonderful!

I have used it successfully a dozen or so times with zero issues, and am grateful for it!
