Select the record with 0x0 inside the field by using Filter

[benny.lbs]

I have a simple testing job as below
Row Generator --> Transformer --> Filter --> Peek

APT_STRING_PADCHAR = 0x0

Row Generator
A: String[1]
B: String[10]

Transformer
C: String[10] = A
D: String[10] = B

Filter
Peek1 <-- C like '%0x0%'
Peek2 <-- D like '%0x0%'


From above design, field C should contain '0x0' inside, however, the filter can not select them out.

Anyone know how to select the record with '0x0' inside the field by using Filter ?
