and where or how do you want to use the string?
I don't know when you make custom files you can depend on the autoloading to load the file, probably you would have to do something like
Code:
$this->lang->load('custom_file_lang');
$this->lang->line('showstring');
It doesn't matter if you call it pt-br or brazilian, it's where you feel most comfortable with.
