Internet Society Requests For Comment (RFCs)
The Point-to-Point Protocol (PPP)  provides a standard method for transporting multi-protocol datagrams over point-to-point links. PPP also defines an extensible Link Control Protocol (LCP), which allows negotiation of an Authentication Protocol for authenticating its peer before allowing Network Layer protocols to transmit over the link.

The Point-to-Point Protocol (PPP)  provides a standard method for
transporting multi-protocol datagrams over point-to-point links. PPP
also defines an extensible Link Control Protocol (LCP), which allows
negotiation of an Authentication Protocol for authenticating its peer
before allowing Network Layer protocols to transmit over the link.
Both LCP and Authentication Protocol packets may contain text which
is intended to be human-readable [2,3,4]. This document defines an
LCP configuration option for the negotiation of character set and
language usage, as required by RFC 2277 .
2. Specification of Requirements
In this document, the key words "MAY", "MUST, "MUST NOT", "optional",
"recommended", "SHOULD", and "SHOULD NOT" are to be interpreted as
described in .
3. Additional LCP Configuration Option
The Configuration Option format and basic options are already defined
for LCP .
Up-to-date values of the LCP Option Type field are specified in STD 2
. This document concerns the following value:
The Internationalization option described here MAY be negotiated
independently in each direction.
Only one instance of this option SHOULD be sent by an implementation,
representing its preferred language and charset.
If Internationalization option is rejected by the peer, the default
language and charset MUST be used to construct all human-readable
messages sent to the peer.
This Configuration Option provides a method for an implementation
to indicate to the peer both the language in which human-readable
messages it sends should be composed and the charset in which that
language should be represented.
A summary of the Internationalization option format is shown below.
