You are rigth, DOS does not regonize those characters, perhaps i will change the name for normal characters, but tell me something:
I changed manual in httpd.conf, added this line:
Include "D:/wamp/apache2/conf/alias/teste.conf"
and create a file teste.conf in alias directory with this code:
Alias /teste/ "d:/João Gonçalves/"
<Directory "d:/João Gonçalves/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order allow,deny
Allow from all
</Directory>
but still the Apache didn't start, and don't thing APACHE use DOS to start, then the problem is not DOS
