+\note{Passwords are limited to a subset of the ASCII character set.
+Versions of this module prior to 2.2.3 were extremely limited.  Starting
+with 2.2.3, all ASCII punctuation is allowed in passwords.  However, note
+that whitespace and non-printable characters are not allowed in passwords.
+This is a limitation of the way the .netrc file is parsed and may be removed
+in the future.}
