Carlos, it's a bit tricky in VFP6.

First, you probably should use .responseBody instead, because there is no transformation of what is sent by the server (beware, it's a byte array so you need to address it as an array, not as a string).

Then, you need to convert the UTF-8 to ISO-Latin-1. Since you don't have anything native in VFP6 for that, you must build your own conversion. If you're only needing to take care of the basic Latin UNICODE block (that's what is required for Portuguese), then this will do:

oHTTP = CREATEOBJECT("WinHttp.WinHttpRequest.5.1")
WITH oHTTP
.Open("GET", m.lcURL, .f.)
ENDWITH
oHTTP.send()
m.the_name_array = oHTTP.responseBody
m.the_name = ""
m.ind = 1
do while m.ind < alen(m.the_name_array)
	m.ch = m.the_name_array[m.ind]
	do case
	case chr(m.ch) == 'Â'
		m.ind = m.ind + 1
		m.ch = m.the_name_array[m.ind]
	case chr(m.ch) == 'Ã'
		m.ind = m.ind + 1
		m.ch = m.the_name_array[m.ind] + 64
	endcase
	the_name = the_name + chr(m.ch)
	m.ind = m.ind + 1
enddo
? m.the_name

Good Morning Mr. Antonio
Sorted out.
I changed the expression:
oHTTP = CREATEOBJECT("WinHttp.WinHttpRequest.5.1")
for
oHTTP = CREATEOBJECT("MSXML2.ServerXMLHTTP.6.0")
Thanks for all
