There are different
mobi formats. The older formats up to
mobi6 and the new
mobi8/
azw3.
The latter has been added since the introducion of new generation kindles (Kindle Touch/Non Touch, Kindle Paperwhite and Kindle Fire). Even Kindle Keyboard latest firmware supports it (not sure about DX)..
As far as I know, if you're reading a old format
mobi with an eInk kindle, the soft hyphens trick does not work (even if you convert a soft-hyphenated
ePub to
mobi).
New kindles (I see you own a K4NT so this is your case) can read
mobi files tailored in three ways:
- old format (mobi6, not supporting soft hyphens but compatible with any kindle device)
- new format (mobi8 supporting soft hyphens)
- "mixed" format (with both mobi6 and mobi8 versions)
They can also read the
AZW3 format which is by all practical means a "new format"
mobi with a different extension.
If you convert an hyphenated
ePub to the "mixed"
mobi format you will see hyphens on your reader because just the
AZW3/
mobi8 part is used. The
AZW3 renderer on the kindle is indeed a distinct application.
In short:
- convert your mobi to ePub;
- add soft hyphens using the plugin;
- and convert it back to mobi ...
- click on "mobi output"
- select "both" (or new) on the "mobi type" drop down menu in the "Kindle output" section
- ... or convert to AZW3 (which is actually "pure" mobi8);
- Upload back to your kindle;
- Read!
Enjoy!
P.S.
Kindle Touch and Paperwhite owners can happily jailbreak their device and install
JBPatch which adds "true" hyphenation support for old format
mobis. This patch gives actually more than hyphenation and I can't use my kindles without it!
However it has a limitation: it can't hyphenate the newer mobi format and that's why this plugin is needed anyway!
