Throughout the document, when it says:

Notes:

The RFC talks about UTF-8 for paths, but not about response messages.
The LANG command specified in the RFC can lead servers to send reply messages containing character outside of the ASCII character set.
It should specify that UTF-8 should also be used for reply messages.
--VERIFIER NOTES--

Section 4.1 says:

This specification RECOMMENDS that the server
default language be English encoded using ASCII. This text may be
augmented by text from other languages. Once negotiated, server-PI
MUST return server messages and textual part of command responses in
the negotiated language and encoded in UTF-8.
