module Net::IMAP::StringPrep::NamePrep

Defined in RFC3491, the nameprep profile of “Stringprep” is:

used by the IDNA protocol for preparing domain names; it is not designed for any other purpose. It is explicitly not designed for processing arbitrary free text and SHOULD NOT be used for that purpose.

…

This profile specifies prohibiting using the following tables…:

  • C.1.2 (Non-ASCII space characters)

  • C.2.2 (Non-ASCII control characters)

  • C.3 (Private use characters)

  • C.4 (Non-character code points)

  • C.5 (Surrogate codes)

  • C.6 (Inappropriate for plain text)

  • C.7 (Inappropriate for canonical representation)

  • C.8 (Change display properties are deprecated)

  • C.9 (Tagging characters)

IMPORTANT NOTE: This profile MUST be used with the IDNA protocol. The IDNA protocol has additional prohibitions that are checked outside of this profile.
