UnicodeDecodeError . . .

[JohnnyCoffee]

Python tries to decode the content of the file as utf-8. You are presumably opening it with "open(path-to-file)" or "open(path-to-file, 'r')" but ought to open it with "open(path-to-file, 'rb')", 'b' for binary.

The error message stopped being displayed on the terminal, but the problem is that the figure does not render (black background appears with a white square in the middle) follows the screen print:



Here is the changed code:

# faz o loop no array comparando as extensões :
        while v_ext in a_ext:
            # Atribui path ao diretorio de arquivos estaticos, memoriza path na variable :
            v_filedir = "web/" + v_app + "/" + v_ass + "/"

# Compara se extensões são as mesmas :
            elif v_ext == ".png":
                # Acessa o arquivo static requisitado :
                o_file = open(v_filedir + "fgs/" + o_fame, "rb")
                # Faz a leitura do arquivo :
                s_file = o_file.read()
                # Variable : obtem status de resposta para client browser :
                status = "200 OK"
                # Variable : obtem cabeçalho http para o browser do client
                headers = [("Content-type", "image/png; charset=utf-8")]
                # Function : Envio de variable para o client browser :
                start_response(status, headers)
                # Output a requisição do client browser:
                return s_file
