I have kindle basic and ilike to read newspaper fetched by calibre. But the problem is that default input set by calibre to fetch newspaper is .mobi which does not support custom fonts in Kindle device. So i convert the newspapers from .mobi to .azw3 and transfer the files to Kindle using usb. Then AZW3 files of newspaper not shows ToC as of .mobi format . So can there any way i get same ToC output in azw3 as .mobi ?
or
Can there any way .mobi support custom fonts in kindle device?
thanks
