I must admit that I never used this stupid multi language thing, but the
general idea is that you can specify offsets for the strings. The base
offset is 0x100 and thus the attributes 0x100, 0x101 and 0x102 gives you
the correct strings.

So looking at the DUN record the extra strings must be at 0xd800 + 0,
0xd800 + 1, 0xd800 + 2, 0xd803 + 0, 0xd803 + 1 etc. But I don't see any
attributes there and this means that this SDP record is incomplete. I
looked at the sdptool code to verify that we request all attributes and
indeed I saw the range 0x0000 - 0xffff which should include the 0xd8xx
attributes.

What kind of broken device is this? Maybe you wanna give sdptest from
libs2 a try.

Regards

Marcel
