Error in replacing special chars using awk


I have a file with following data :
a$cd
e%gh
I am trying to replace the special chars with space.
When I execute the following command these chars are replaced :
awk '{gsub(/[\041-\177]/,"b",$0);print $0}' temp.txt

Result:
abcd
ebgh

But when I execute
awk '{gsub(/[\041-\175]/,"b",$0);print $0}' temp.txt

Result:
a$cd
e%gh

these chars are not replaced.Could someone tell me if I am doing any mistake.

Thanks in advance

I have to investigate the reason of this strange behaviour more in depth, but in the meanwhile why don't use
Code:
gawk '{gsub(/[[:punct:]]/," ",$0); print}' temp.txt
