Sql-server – FOR XML could not serialize the data because it contains character (0x0000)

I have a big query (if necessary I will post it here) and I'm getting this error:

Msg 6841, Level 16, State 1, Line 1
FOR XML could not serialize the
data for node 'NoName' because it contains a character (0x0000) which
is not allowed in XML. To retrieve this data using FOR XML, convert it
to binary, varbinary or image data type and use the BINARY BASE64
directive.

The only part I use FOR XML is here:

WHERE 
    (CodFuncionario = Results.CodFuncionario) 
FOR XML PATH(''), TYPE).value('(./text())[1]', 
    'VARCHAR(MAX)'), 1, 2, '') AS [Experiencia]

But, what is node noname? and how can I look for this value: (0x0000)

This is one of the subqueries (the only part I have FOR XML):

SELECT 
    [CodFuncionario],
    STUFF
    (
        (
            SELECT 
                ' / ' + 
            CAST
            (
                [DescFuncao] + '-' + 
                [DescTempoExperiencia] 
                AS VARCHAR(MAX)
            )...
FROM 
    [Linked_Server].db.dbo.tblFuncionarioExperiencia T0
INNER JOIN
    [Linked_Server].db.dbo.tblFuncao T1 On T0.codFuncao = T1.CodFuncao
INNER JOIN
    [Linked_Server].db.dbo.tblTempoExperiencia T2 ON T0.CodTempoExperiencia = T2.CodTempoExperiencia 
WHERE 
   (CodFuncionario = Results.CodFuncionario) 
   FOR XML PATH(''), TYPE).value('(./text())[1]', 'VARCHAR(MAX)'), 1, 2, '') AS [Experiencia]
  FROM 
      [Linked_Server].db.dbo.tblFuncionarioExperiencia Results  
  GROUP BY 
      CodFuncionario) as T2

  On T0.CodFuncionario = T2.CodFuncionario

Left Join...
