node-red-node-firebird returns a buffer instead of a string - buffer

Question

I'm doing KPI's in node-red, and I'm using node-red-node-firebird to connect my database and get the results from it. For that I made a query to select the columns I need, one of those is:
NAME Varchar(40), with an example value: "Pizzas"
(example: Select NAME from mytable)
When I receive the query response on node-red, I store it inside the msg.payload. The problem is the result that I get it isn't the string "Pizzas" but a buffer "NAME":{"type":"Buffer","data":[80,105,122,122,97,115]}}.
How can I get the string and not the buffer?
I already tried a lot of things, among them:
On the query I have tried cast(NAME AS varchar(40)) AS NAME; [NAME] without success. Put msg.payload.data.toString('utf-8') in function node but nothing happens, the function:
var objectData = msg.objectData; //this is the query response
//------------Columns----------------------------
var fields = [];
var i = 0;
if(objectData.length > 0) {
var data = objectData[0];
for(var key in data) {
fields[i] = key;
i++;
}
//TRY nº1
objectData.foreach(function(obj){
if (Buffer.isBuffer(obj) === true) {
obj = obj.toString('utf-8');
}
})
}
//-----------------------------------------
msg.method = "POST";
msg.url = //My api request//;
msg.headers = {};
msg.headers["Content-Type"] = "application/json";
msg.headers.Authorization = //auth//;
msg.payload = {
'groupID': 'Group123',
'companyID': 1221,
'table': 'DemoTable',
'fields': fields,
'data': objectData, //problem
'delete': true,
};
//TRY nº2
msg.payload = msg.payload.data.toString('utf-8');
return msg;

I solved my problem changing the select to:
SELECT cast(name as varchar(100) character set win1252) NOME FROM mytable
Thanks for the help :)
