Unicode in passwords

[Yoriyuki Yamagata]

Dear John,

FYI, IETF is working on this issue.  See Internet Draft https://tools.ietf.org/html/draft-ietf-precis-saslprepbis-17 based on PRECIS framework RFC 7564 https://tools.ietf.org/html/rfc7564

Best,

> I'm researching potential problems and best practices for password policies that allow non-Latin-1 Unicode characters. My searching of the unicode.org site showed me a general security considerations document (UTR #36) but nothing specific for password policies using Unicode.
> 
> Can you recommend any documents to help me understand potential issues (if any) for password policies and validation methods that allow characters from more "exotic" portions of the Unicode space? 
> 
> Best regards,
> John O'Conner
