I have checked the source code carefully. First we log using the
formatter %S which displays quotes and escapes special characters:
dlog#f 3 "Synthetizing %S to %S" s local ;
Then we call the synthesis script in a very direct way, passing s as
it is, without escaping or anything:
execv cmd [| cmd;s;local |]
In your logs, you saw:
Synthetizing "Now playing - M\246bius - Untitled Track" to
"/tmp/say19ebd4.wav"
I have checked that it means that the special character \246 appears
as such in the string s passed to the script. The string s does not
contain four characters including the backslash, otherwise the
backslash would be escaped when displayed using %S. Here is an OCaml
session showing this:
# let s = "\246" ;;
val s : string = "\246"
# String.length s ;;
- : int = 1
# Printf.printf "%S\n" s ;;
"\246"
- : unit = ()
# let s = "\\246" ;;
val s : string = "\\246"
# String.length s ;;
- : int = 4
# Printf.printf "%S\n" s ;;
"\\246"
- : unit = ()
So the problem must be in one of the next steps. The only thing I can
see is in the liquidtts script, where we have (in a context where $1
refers to our string s above):
echo $1 | @TEXT2WAVE@ -f 44100
Right now, I'm a bit puzzled regarding what could go wrong, and how
the shell should behave regarding this echo $1.

This might be your shell doing something with the accent. The special
charcter \246 is latin1; does your shell use the same charset?
