微電腦 - ASUS C100P - Debian 10 - 解決FAT-fs (sda1): IO charset ascii not found問題

問題如下：

$ sudo mount -t vfat /dev/sda1 /mnt
  mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error.

$ sudo dmesg -c
    [ 1000.021566] FAT-fs (sda1): IO charset ascii not found

解法如下：

$ sudo mount -t vfat -o iocharset=utf8 /dev/sda1 /mnt
$ sudo dmesg -c
    [ 1010.694003] FAT-fs (sda1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
