Mount FAT32 USB flash drive with cyrillic filenames on FreeBSD

To mount:

# mount_msdosfs -D UTF-8 -L en_US.UTF-8 -u 1001 /dev/da0s1 /media/usb

Replace 1001 with your user id and /media/usb with your actual mountpoint.

To unmount, make sure no one uses the directory, then as usual:

# umount /media/usb
