Edit Latex on Vim and Aspell - Accents

Hello, I'm trying to use VIM to edit a file in Latex. When writing the text in Latex in the same I do accent normally, having difficulty to correct the same in Aspell or Texmaker:

I write in VIM: *estratégicas*

Appears in Aspell: *Estrat\égicas*

This way I can not correct the spelling of my text.

I already include in the preamble of my file .tex :

\usepackage[portugues]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{aeguill}

Is there any way I can save the .tex file in the way I can use Aspell or Texmaker?
