calibredb strange behaviour

[webwizard]

I am still missing something.

I try to pull out the OPF structure using:

calibredb show_metadata --as-opf 1127 >zzzzz.txt

and immediately typing

calibredb set_metadata 1127 zzzzz.txt

produces this error:

Python function terminated unexpectedly
  'charmap' codec can't encode characters in position 280-283: character maps to
 <undefined> (Error Code: 1)
Traceback (most recent call last):
  File "site.py", line 103, in main
  File "site.py", line 85, in run_entry_point
  File "site-packages\calibre\library\cli.py", line 1183, in main
  File "site-packages\calibre\library\cli.py", line 483, in command_set_metadata

  File "site-packages\calibre\library\cli.py", line 459, in do_set_metadata

  File "encodings\cp1252.py", line 12, in encode
UnicodeEncodeError: 'charmap' codec can't encode characters in position 280-283:
 character maps to <undefined>

What's the catch ? I attached the xxxxx.txt file and the original metadata.opf from Calibre DB.

redirect the output from show_metadata to a file. The windows console in its default configuration cannot handle unicode output very well.

Good advice. How do I do it ?

[kovidgoyal]

the same way you did it in your first command

Well, something has to be changed, since what I did in the first command results in an error. Doing it in the same way yeld the same result...

Ah you have characters in your metadata that cannot be encoded in mbcs. Dont worry about the error, it just means calibre failed to print out the updated metadata. The metadata will still have been updated.

So I can ignore the error and go on ?

OK, it seems that removing the unicode characters in the custom field from Calibre GUI and redoing the whole cmd procedure, things work again.

I'll deal with that in a different way.

Thanks
