#86 wrong encoding in pt_BR messages file

the file data/languages/ptbrazilian/messages has enconding latin1, but when the text is added in an squid html, the squid html has enconding utf-8. So, half the page has one enconding and the other half has another enconding.

I suggest replace the file by another, with changed enconding (utf-8). the file converted to utf-8 is attached. the file was taked from the dansguardian-2.12.0.0
