False. The web page describes in detail one ACE proposal and its costs,
and then one UTF-8 proposal and its costs. Many programs need updates
and redeployment only for ACE.

False. The UTF-8 proposal analyzed on my web page involves redeployment
of only a few programs.

> If it has a presentation layer

Please give a clear definition of ``presentation layer,'' and explain
which of the following programs have ``presentation layers'': named;
dents; tinydns; tcpclient; telnetd; sshd; tcpd; tcpserver; fetchmail;
apache; boa; fhttpd; gn; mathopd; publicfile; roxen; thttpd; webfs; wn.
Those are some of the programs that have to be upgraded and redeployed
for ACE.
