I am cutting and pasting Portuguese text into a LaTeX file (to translate an article that has a lot of math and graphics). It is working fine. I use:
\usepackage[brazil]{babel}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
But the source file is being spellchecked in English as I go, working in WinEdt 9.0.
I can live with that if there is no easy alternative. But is there an easy way to get WinEdt 9.0 to spellcheck the source file in Brazilian Portuguese?
