How can we have a comma? (",")

I am experiencing a problem regarding the comma character (",") when I am trying to define it as part of the password. Please look at the examples:


Static word (space between 2 words): Pretty Secret
oclhashcat64.exe -m 1400 SHA256.txt --username -1 1234567 -a 3 "?1?a?a?a?aPretty Secret"

Works fine!


Static word (space and "?" between 2 words): Pretty ? Secret
oclhashcat64.exe -m 1400 SHA256.txt --username -1 1234567 -a 3 "?1?a?a?a?aPretty ? Secret"
ERROR: syntax error

Adding a 2nd "?" does the trick: oclhashcat64.exe -m 1400 SHA256.txt --username -1 1234567 -a 3 "?1?a?a?a?aPretty ?? Secret"
success!


Static word (space and "," between 2 words): Pretty, Secret
oclhashcat64.exe -m 1400 SHA256.txt --username -1 1234567 -a 3 "?1?a?a?a?aPretty, Secret"
ERROR: syntax error

Adding a 2nd "," does not work. Adding a "\" before the "," does not work either.

So, how can we have a comma (",") for this kind of configuration?
