Dave mentioned the client potentially crashing. I don't buy that. An FTP client can obviously handle ASCII if the desired LANG is not supported, so then it's going to crash when it sees the same characters when another language is negotiated but it otherwise sees the same text. It's not like 7-bit ASCII characters never occur in languages that use other scripts.

Maybe at this point in the discussion it would be good to hear from implementers. There are already tons of NAT44 FTP ALGs out there, I wonder how those solve this.
