Handling unicode data in XMLRPC
This issue comes from Kettle.
My program is using Kettle to get an Excel file, get the active sheet and transfer the data in that sheet to TerminateOOOR for further handling.
At the phase of reading data from Excel file, Kettle can not recognize the encoding then it gives bad data to TerminateOOOR.  
My work around solution is manually exporting excel to csv before giving data to TerminateOOOR. By doing this, I don't use the feature to mapping excel column name a variable name (used by kettle).
I have to migrate data to OpenERP through XMLRPC by using TerminatOOOR.
I send a name with value "Rotule right Aurélia".
In Python the name with be encoded with value : 'Rotule right Aur\xc3\xa9lia '
But in TerminatOOOR (xmlrpc client) the data is encoded with value 'Rotule middle Aur\357\277\275lia'
So in the server side, the data value is not decoded correctly and I get bad data.  
The terminateOOOR is a ruby plugin for Kettle ( Java product) and I guess it should encode data by utf-8.
I just don't know why it happens like this.
Any help?
