space between lines \huge

I created a title page for my thesis. I used the code \huge for title. But, my title has words with accents. So, the space between first e second line is different than second and third line.

Could you give a Minimal Working Example of code producing such a result? Normally inteline spacing has nothing to do with the presence or not of accented letters. – Bernard Jun 7 '14 at 18:47

TeX uses the \baselineskip setting that is active at the end of the paragraph. If the group, where \huge is set, is closed earlier, then the settings before (\normalsize?) is used, too small for huge text. Then TeX switches to \lineskip that separates the lines, usually 1pt. The first line has a cedilla and the second line accented characters. Thus the space looks greater, but the space between the cedilla and the accent is probably just 1pt.

\documentclass{article}
\usepackage[hmargin=20mm]{geometry}
\begin{document}
{
\centering
\huge
MODIFICA\c C\~AO DE CARBONATO DE\\
C\'ALCIO NATURAL COM S\'ILICA PARA\\
APLICA\c C\~OES EM PAPEL
\par % close paragraph explicitly before group end
}
\end{document}

Without MWE I am only guessing the real source of the problem. However, I am nearly sure that it is not the matter of accented letters, but the lack of final \par in a structure producing the title, e.g.

\begin{center}
\huge
First line\\
Second line\\
Third line
\par % or free line
\end{center}

\par isn't needed in this case (well it is, needed but \end{center} supplies one so an extra one is not neeed). – David Carlisle Jun 7 '14 at 20:51
