First headline level with =-character
Second
Third
... (up to "Fifth")
If a headline isn't displayed correctly, it is usually because:
there are invisible (whitespace) spaces after the concluding =-character (they can be deleted manually or with "Remover espaço em branco no final de cada linha" edit option).
- the number of =-characters at the front and at the back doesn't match.
