Comment 4 for bug 468343

Ah, so it seems that blkid is not able to read the label that ntfslabel set. I can reproduce this:

$ sudo mkfs.ntfs /dev/ram0

works fine for ascii:

$ sudo ntfslabel /dev/ram0 ascii
$ sudo blkid -p /dev/ram0
/dev/ram0: UUID="340F594C06D212D8" LABEL="ascii" TYPE="ntfs" USAGE="filesystem"

when mixing ASCII and some German umlaut/Euro sign, output becomes scrambled:
$ sudo ntfslabel /dev/ram0 'aäo€xx'

$ sudo blkid -p /dev/ram0
/dev/ram0: UUID="340F594C06D212D8" LABEL="aM-do?xx" TYPE="ntfs" USAGE="filesystem"

Chinese characters aren't detected at all:

$ sudo ntfslabel /dev/ram0 'dong西xi'
$ sudo blkid -p /dev/ram0
/dev/ram0: UUID="340F594C06D212D8" LABEL="dong?xi" TYPE="ntfs" USAGE="filesystem"
