[texhax] How to put space characters at the beginning of a line?

[José Romildo Malaquias]

Hello.

I need to put space characters at the beginning of a line in a LaTeX
document. The problem is that neither '~' nor '\ ' works to achieve this
behaviour.

See the simplified document that illustrates the problem:

   \documentclass[a4paper]{article}

   \begin{document}

   \ttfamily\frenchspacing\noindent
   First~line\newline
   ~~Second~line

   \end{document}

Note that, when this document is compiled, the letter 'S' in the last
line aligns to the letter 'F' in the previous line. How can I get this
'S' aligned to the 'r' front the previous line?

This problem should be solved without using the verbatim (or similar)
environment.

Regards,

Romildo
