How do I add utf8 to a certain mounted device?

[Xamindar]

I have searched the web all day for the answer but all I can find is
stuff about fstab-sync, old versions of hal.

I have a Zaurus that mounts as a usb flash drive.  I need it to mount
with utf8 so I can read and copy over filenames that are in Japanese. 
At the moment I have to unmount it when hal mounts it and mount it
manually with the option.

Is there a way to have Hal mount this device with utf-8?  If not then
I'm fine with having all my usb sticks mounted with utf-8.

By the way, where is the documentation for hal?  I can't find much at
all, and the stuff I do find is distribution specific and outdated.

Thanks for any help.
