Encoding problem editing portuguese language file

Hello,

I'm trying to modify the defines of moneyorder payment module, and I put some html tags there.
My problem is, I'm writing in portuguese, changing the portuguese "version", and I'm having an encoding problem!
I made everything I could to fix it, and the only thing that worked was put a header('charset'), it fixed the moneyorder define but broke the encondig of another things.

Regards,
Letícia.

Not sure what exactly you mean by "encoding problem". Do you mean you have a problem with your editor? or an error on your website? or a PHP error? etc?
What exact header() code did you add?

Are you saving your language files with the proper encoding when your text-editor saves the file?

Ok, i'll try to explain it better:
I'm trying to activate the money order payment module, and I have to write the defines in english and portuguese too, and portuguese word has orthographic accent, when i try to modificate the defines at languages/portuguese/... the words are shown with an encoding problem! And I can change de charset because all of the others defines and modules. Could I explain better?

1. Copy /includes/languages/**english/**modules/payment/moneyorder.php to /includes/languages/**portuguese/**modules/payment/moneyorder.php
2. Use a reliable text editor on your PC (such as Notepad++ http://notepad-plus.sf.net ) to edit /includes/languages/**portuguese/**modules/payment/moneyorder.php ... make your translations, and save the file. When saving the file, use the correct encoding for that language.
3. Upload the /includes/languages/**portuguese/**modules/payment/moneyorder.php file to your server.
