KEY commands containing unspeakable characters

[Gary Cramblitt]

When I send characters in the latin-1 charset > 128 to SD via !KEY command, 
example

@ U+00AF
!SPEAK
Macron:
.
!KEY ¯

@ U+00B4
!SPEAK
Acute accent:
.
!KEY ´

!QUIT

SD does not speak the characters using Festival.  In the IBM TTS output module 
I am working on, I found that IBM TTS does a decent job of speaking these 
characters.  I only had to fix a few of them.  I did this by creating a 
simple configurable mapping table in ibmtts.conf and replacing the characters 
with speakable words when the output module receives a KEY command.  I'm 
wondering if we should consider generalizing this capability to all output 
modules/synths.

One issue is that the speakable names of characters are language dependent.  
It would be best if each synth handled this itself, but of course, most 
don't.  So what's the right level to address this issue?  SD Server or output 
module for each synth?
