Xarchiver and non ASCII file names problem

[WhizzoCode]

Hi, first of all, sorry about my bad english.
I installed Fedora 17 XFCE Spin.
The language is Spanish.
When I try to decompress a zip file in Xarchiver, if the zip file contains a non ASCII file name, can't view or extract.
Example:
In Terminal I create a zip, with a non ASCII file in:

$ echo text > áéíóúñ.txt
$ zip zip_file.zip áéíóúñ.txt

If I try to open zip_file.zip with Xarchiver, the content file apears as ??????.txt.
If I try to view the file this message apears:

Archive:  /home/sergio/Escritorio/zip_file.zip
caution: filename not matched:  \?\?\?\?\?\?.txt

Same result if I try to extract the áéíóúñ.txt file.
My /etc/sysconfig/i18n is:

LANG="es_ES.UTF-8"
SYSFONT="latarcyrheb-sun16"

What can I do?
Thanks
