Hi Kovid,

I don't know if you've noticed the matter in the Apple forum, but an issue has arisen with Calibre-generated ePub files in the new versions of the "iBooks" bookreader for iPad and iPhone. iBooks has a language-specific dictionary, and all ePub files generated by Calibre appear to contain a "dc:language" metadata value of "UND", resulting in an inability to use the dictionary. Editing the metadata value to "EN" makes the dictionary work.

Three questions:

1. Can Calibre generate a default language metadata value of "EN" rather than "UND"?

2. Would it be possible to edit this value in Calibre's "Edit Metadata" screen?

3. When Calibre converts a Mobipocket file containing a valid language metadata value, even then it still produces the "UND" value in the ePub. Would it be possible to correctly import this value from the Mobipocket file?

I would enter this on the project tracker, but unfortunately it doesn't seem to want to let me log on at present.

Thanks!
