sed problems with hexadecimal substitutions

[Andre]

I'm trying to use Busybox sed for quick and dirty UTF16 to ascii
conversion:

$ xxd tst.uft16 
0000000: 6100 6200 6300 3100 3200 3300 0a         a.b.c.1.2.3..

GNU sed version 4.1.2 gives the expected result:

$ sed 's/\x00//g' < tst.uft16 | xxd
0000000: 6162 6331 3233 0a                        abc123.

Busybox 1.3.1 sed doesn't seem to do anything:

$ busybox-1.3.1 sed 's/\x00//g' < tst.uft16 | xxd
0000000: 6100 6200 6300 3100 3200 3300 0a         a.b.c.1.2.3..

Busybox 1.2.1 sed removes the \x00 chars, but then adds spurious
newline chars after every conversion...

$ busybox-1.2.1 sed 's/\x00//g' < tst.uft16 | xxd
0000000: 610a 620a 630a 310a 320a 330a 0a         a.b.c.1.2.3..
