Seems that from the latest update of Windows the console is not working well.
I mean the console attached to a GUI application, for debugging purposes.
Sometimes it displays nothing, some times it displays but not the entire text, and it displays badly the non ASCII characters- Like latin characters with tilde.
According to the setting of my console, it says Codepage 850 (OEM - Latín Multilingüe)
How I can fix it? I tried the setting "Using the inherited console" (or whatever it translates "Usar la consola heredada") without success.
