Any application that uses the htt input method server to receive Simplified Chinese characters must find htt running before it can receive input. If your default locale is the C locale (which does not require htt) and you then change from C to another locale in a single Terminal, for example, you must start htt with a command line like the following:
system% /usr/openwin/bin/htt -if cle -xim htt_xbe & |
With the locale set to zh, htt starts automatically when the Simplified Chinese windowing environment is started. In CDE, htt is started from a script, /usr/dt/config/Xsession.d/0020.dtims. This script is executed by Xsession, which runs at every initialization stage when a user logs in from dtlogin. This script ensures that htt is started before other applications in CDE.
