People occasionally ask for PuTTY to interpret escape codes in the banner some SSH servers send prior to authentication.
The SSH-2 authentication specification,
RFC 4252,
states, in the section about SSH_MSG_USERAUTH_BANNER
:
If the 'message' string is displayed, control character filtering, discussed in [SSH-ARCH], SHOULD be used to avoid attacks by sending terminal control characters.
This is what PuTTY does, and as such, terminal-control sequences won't work.
Audit trail for this wish.
