OK
Looks like my job for today, is update my Calibre and load the plugin.
(Doitsu thanks for the tip about character lists)
Not sure why Previewer is categorising the characters as Arabic/Indic they are mostly Nordic/Germanic type, ie English with accents and a few ae ligatures.
(My friend the author has been instructed not to write any more of this elf-nonsense, but he will probably ignore me)
The first 2 volumes uploaded OK but that was about 4 years ago. I really need to revisit them after I sort out Vol 3.
Not sure what Amazon may have done with them recently as they "threaten" in their guidlines, to update books to their new advanced typesetting mode.
Thanks for all the help, guys,
