FAT32 can't be mounted - IO charset iso8859-1 not found

[kaefert]

With a fresh installation of Linux Mint 15 Cinnamon 64bit Edition on my Asus Zenbook UX32VD the system won't correctly boot, since it is not able to mount its EFI FAT32 partition. It will print this error every time I (or it) tries to mount the partition:
FAT-fs (sda1): IO charset iso8859-1 not found

This bug also affects me on a fresh install of Linux Mint 14 MATE on a Dell e6400 laptop, having previously been used in LM13. In my case I get the following error when trying to mount any external drives or USB stick:

Status changed to 'Confirmed' because the bug affects multiple users.

I've solve this issue for me by NOT using unetbootin to create the installation media but using dd to write it directly to the usb-stick-device-file (ignoring partitions) [or a gui tool that does exactly that like the linux mint usb image writer]

I've tried lots of different versions 13.10, 64bit 13.04, mini iso etc. normal etc.

They did not work on efiboot and raid5 - after using 13.04 secure...and boot-repair, I was able to find why, the kernel doesn't supports to mount Fat32 with iso8859-1 but that is what is on my efi partition. So it isn't possible.

I do not know how to get rid of this and try now to install a different kernel but I do know that the kernel 3.8.0-19-generic is working with it, because this kernel does it on my system at the moment I've not tried to build up my own kernel but looks like I need to do. Will now check if the extra is working but that seems than to load al while more because of its size.

My system refused to boot after updating and after much debugging I finally figured out how to get my hidden GRUB menu to show (ESC works but neither shift key works for me). I edited the GRUB line to be able to figure out what the error was and saw "FAT-fs (sda2): IO charset iso8859-1 not found" (/boot is sda1 and EFI is sda2).

I tried booting from a previous kernel version (3.16.0-33) and it seems to work, while the current version (3.16.0-34) gets stuck every time.
