Thanks for your quick reply. Finally, I have come to final solution to meet all of my requirements for reading manga on Kindle devices under Macosx Mavericks 10.9.2 with the combination of Acidweb and HarryT suggestions. The process is described as follows:
Manga for KPW2 with no margin, Panel View support, TOC & standard cover & metadata (UTF-8 unicode) without jailbreak to use JBpatch, coolreader and hack font on KPW2
1/ Kindle Comic Converter (KCC) epub/ horizontal/ strech/ kindle paperwhite (using folder structure for KCC to converted with TOC as Acidweb suggested here
https://github.com/ciromattia/kcc/wi...tput-splitting) (if using UTF-8, you should embed font "Arial Unicode" from system font). If you are not using UTF-8, choose mobi format for a final go.
2/ If you have problem with UTF-8, Sigil or Kindle Comic Creator (KC2): add font "Arial unicode" to epub (2) and change metadata with Sigil easily or using MobiMetaEditorV016 in mobiread forum
3/ Kindle Previewer (Kindlegen) --> mobi
4/ Strip mobi (3) by Kindle Stripper --> final mobi
5/ Calibre book cover: 1.6 ratio for book cover (1600x1000) and upload to your Kindle devices.
Thanks for all of your advice (especially to Acidweb and Harry T) million times!
