[Voiceglue] Using ISO-8859-1 as XML encoding

[emiliano esposito]

Hi all,

I need to synthetize into italian language, and festival won't like 
UTF-8 strings.
So I ask you if it's someway possible to have vxml files encoded into 
ISO-8859-1.

I tried with:

<?xml version="1.0" encoding="ISO-8859-1"?>
<vxml version="2.0" xmlns="http://www.w3.org/2001/vxml"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.w3.org/2001/vxml
http://www.w3.org/TR/voicexml20/vxml.xsd"
xml:lang="it">

But when the first italian character (for instance: "è" ie &egrave; in 
HTML) shows up, I get an error.
I think it's due to the SSML translation done by OpenVXI, that simply 
returns "<?xml version='1.0'?>" and won't set a proper encoding for its 
content.

Is it possible to change this behaviour?

Thanks.

The error log follows:
