MobileRead Forums - View Single Post - Error importing/editing metadata with files from Feedbooks

I have recently downloaded four e-books from Feedbooks (actually only two, but one of them in three different formats), and Calibre 1.48 (Windows, x64) is having problems processing them. The problem seems to be unrelated to any specific format; it's happening with all of them (the books are in MOBI, ePub and PDF, and the same problem is happening with all of them).

First, when I add the book to the library, the Management module shows the message:

WARNING: Failed to read metadata originating from:

The detailed message is in the spoiler below:

Spoiler:

In spite of the error, after that the book appears on the Management module's library list, but when I try to open it by double-clicking on the entry, the following message appears (also in Portuguese, I've translated it):

ERROR: Unable to view: [book title] has no available formats

(There is no further detailed message.)

I guess this must be because Management is not copying the e-book file to the library folder or creating the appropriate subfolders.

However, when I open the e-book file directly from Windows Explorer (Calibre is set as my default e-book reader), the Viewer module opens it normally and without any problems. The problem seems to be only in the Management module, which is why I have posted this thread on this sub-forum.

After importing the book, it also appears without the author on the library list in Calibre Management. (Oddly, when I sort the list by author name, the book appears between author letters D and E - the books are by William Olaf Stapledon.) When I try to edit the metadata to include the author, sometimes the author appears correctly in the "Author(s)" field, sometimes in the "Ordered author" field, sometimes in neither, randomly and for the same book. Then I try to edit the blank field, but as I type each single character, the following error message appears:

UnicodeDecodeError:'utf8' codec can't decode bytes in position 1-2: invalid continuation byte

(This message is not localized and appears in English.)

Detailed message:

Spoiler:

Even if I patiently type each character and dismiss the message every time, I can't save the edit, because the message above appears again and the window doesn't close. I have to cancel and lose my changes. The same message also appears if I paste the full text or try to move the "Author(s)" field's contents to "Ordered author" by clicking on the arrow. I'm stuck.

I'm running Calibre on a powerful PC with a hexa-core processor, 16 GB RAM, tons of free disk space, no malware, running Windows 8.1 Update 1 x64.

Any hints to solve the problem? Thank you very much for your help.
