Spanish font failure in Table of Contents

[Robert J. Chassell]

Using

    TeX, Version 3.14159 (Web2C 7.3.7)
    Texinfo version 2001-06-20.16
    texi2dvi (GNU Texinfo 4.2) 0.51

After conversion via TeX to dvi some of the Spanish titles in the
Table of Contents have broken fonts when I look at the output with
xdvi.  I have not seen any broken fonts in any other part of the
document.

Here is a test file that illustrates the problem.  Convert to dvi
using TeX and view using `xdvi'.

    texi2dvi Spanish-font-test.texi

    xdvi Spanish-font-test.dvi &



\input texinfo.tex   @c -*-texinfo-*-

@c titles at the same time

Jose C. Miranda, @email{jmiranda@@campus.tol.itesm.mx} has been
translating a speech on software freedom from English into Spanish.

The English text is within

This works fine, except that after conversion via TeX to dvi in the
table of contents, some of the Spanish titles have broken fonts when I
look at the output with xdvi.  I have not seen any broken fonts in any
other part of the document.

After converting this Texinfo file to .dvi, xdvi displays broken fonts
for the Spanish versions for the title of this chapter and for the
titles for the following sections.
