test: do not output non ascii character

The unit test for content |aa bz| transforms in place the string
str to replace the 2 characters aa by one character 0xaa
Then, when z is not recognized as a valid hexadeicmal character,
the whole modified string is printed out, inclusing the non-ascii
0xaa

Ticket: #5558
