Hi Michael,

The "junk" characters are probably the one the user entered when giving a label
to the partition. I don't think its value is supposed to be "EFI system
partition".

The partition label is retrieved by udev via libblkid, in fact you can probably
see the same chars with blkid(8).

And it's not related to the locale settings at all.

I would use the partition type GUID which is
C12A7328-F81F-11D2-BA4B-00A0C93EC93B for ESP.
