k3b can't burn files with encoding problems

Further, after this happens, k3b crashes, and k3b won't start again until the computer is restarted (if you try, it just hangs).

Please could you supply some more information:

what version of kubuntu and k3b are you using?
what type of CD were you trying to create?
i presume the character is "é"?
what is the exact error from k3b (you could use ksnapshot to take a screen shot of the error and attach it)?

Thanks for the speedy response.

KDE v 3.5.2
K3b 0.12.14

The character you presume is correct (I can't type it.) The disk is a data DVD.

I fixed some of the filenames in konqueror, and will do the rest. However, here's the debugging output from k3b:

Actually, two strange things about these;

a) Most of them do not have "little boxes" replacing characters in their names, in the terminal or in konqueror.

b) I tried renaming one of them, and it still was flagged by k3b.

Do you still have the problem?

Yes, except that now when I add the file k3b pops up a dialog complaining, e.g.

The following filenames have an invalid encoding. You may fix this with the convmv tool:
/mm1/music/house & trance & techno & eurocheese/Vincent De Moor - Between Two Fires (Armin van Buuren??s Rising Star Mix).mp3

This is better - at least I'm not making a coaster - but I still consider this a bug, as k3b should be able to handle unicode input. In some software I'm working on right now I wrote some code to "down-convert" unicode characters to latin; if you'd like, I can contribute the algorithm.

Hello.
I do not understand is that what happens in the earlier version had passed songs to mp3 audio CD player without problems, so he could listen to any player who has no mp3, but now I am unable because they are not listening, despite the continuing the same process.
There is no type of error message. If I install library is: sudo aptitude install libk3b2-mp3, which solves the problem, the console tells me: @ Vazquez Vazquez-laptop: ~ $ sudo aptitude install libk3b2-mp3

Hola.
No entiendo que es lo que ocurre, en la anterior versión había pasado canciones de mp3 a cd audio sin problemas, con lo que podía escucharlas en cualquier reproductor que careciese de mp3, pero ahora soy incapaz ya que no se escuchan, apesar de seguir el mismo proceso.
No existe ningún tipo de mensaje de error. Si instalo està libreria:sudo apt-get install libk3b2-mp3, la cual resuelve el problema, la consola me dice: vazquez@vazquez-laptop:~$ sudo apt-get install libk3b2-mp3

The unique difference is the type of gravadora since before this was a piooner DVD on a travel mate acer 4150 and now it is a hp pavilium dv 6000 with a DVD recorder model slimtype A DS8A1H

Thank you for reporting this bug.

Does this issue occur in Lucid?
