Hello,
It's strange, it looks like old Javanese but only the second, fourth and fifth letters seem to be letters from old Javanese script.
I can read
:
? / ꦏ ka or ꦏꦸ ku (= ꦏ ka +ꦸ u ?) / ? / ꦭ ꦴ lā (= ꦭ la + ꦴ ā)
But this is just an attempt at recognizing signs from the Javanese script wikipedia page.
