<FNC1> is included when saving detamatrix

I created a GS1 data matrix.
As stated in the wiki, the GS code was specified as 0x29.
When I read the generated data, the GS code part was ")".
I want the ")" character to be " "
How can I exclude this?

I understand that 0x29 in the ASCII Code table is ")"..
Is 0x29 listed on the wiki an error in 29 (decimal)?
