Thanks Jonas for your valuable comments. Please, have a look at http://lpweb.com.br/dl/enc.html I prepared this table in order to choose which configuration I should use. The best option is UTF-8 source without cwstring, but sometimes I need to link with libraries that uses this unit. What I am missing or which configuration I can change?
