according to RFC1617 (http://www.ietf.org/rfc/rfc1617.txt?number=1617)
heading 4.4.1, a comma is not allowed as part of the common name.

1. The RFC and the section cited above does not say anything about a
comma at all.
2. This informational (and old) RFC was just meant as an profile of
X.500 directories in a special project.
3. The RFC is not relevant here since it talks about directories.
PKIX is relevant, see RFC 3280 (Standards Track).

=> Off course you can use a comma in the CN (alias commonName) if you
encode the subject DN as UTF8String as suggested by PKIX. Even
PrintableString should work.

The main problem with a comma is that it's used as a DN component
separator for the string representation of distinguished names.
Depending on what tools you use and depending on your shell you might
have to escape the comma, e.g. with a backslash \.
