work is going on for #3 : i can read my blog backup, provided it's given as a local file
(strangely enough, trying to directly downloading it result into strange encoding exceptions)
Anyway, once it's done, the next wall to be hit will be the one where all entries of Wordpress export are not blogs (images, as an example, are included)
For #3, I have now working export with the right encoding, correct de-htmlentitizing, and a good way to filter effective posts out of attachments
made sure the UTF-8 constant was always the same
Some work for #6
nuemrous changes making Goodreads export "quite" working : books can now contain more infos, and series are alos written. BUT series and books are not linked together and book presentation is not optimal.
one more improvement set for goodreads export ! will start to work on other subjects otherwsie they'll be postponed forever
