\begin{document}
We do not consider variables and quantifiers for the following reason:
in SEM each input clause with $n$ universally quantified variables
$C(x_1,\ldots,x_n)$ is replaced by the conjunction of the ground clauses
$C(v_1,\ldots,v_n)$ for all possible\footnote{blabla} values $v_i\in D$.
Since the elements of $D$ are not constant symbols, we replace each
value $v\in D$ by a special, new constant symbol $a_v$. These constants are
special because they are given special values in $I$; we take $I[a_v] =
\{v\}$,
and of course we implicitly add them to $\Sigma$. We will not prove that any
first order formula with equality $\psi$ can thus be transformed into a
set of ground clauses $\varphi$, such that searching models of $\psi$ in $D$
is equivalent (through a 1-1 correspondence) to searching models of
$\varphi$ among the refinements of $I$.

The difference is the number of letters on the second line. I think it is

bug.
Hello,
Unfortunately, I am unable to reproduce the bug by using footnotes
with a standard document class.
After further investigations, it seems that the bug appears because
entcls.cls redefines footnotes to use \refstepcounter instead of
\stepcounter.
The following code exhibits a similar bug, using only standard article
class and \refstepcounter:
%%
\documentclass{article}
%\usepackage[pdftex]{hyperref}
%\usepackage[dvips]{hyperref}
%\usepackage{hyperref}
\newcounter{a}
\newlength{\La}
\newlength{\Lb}
\begin{document}
\setlength{\La}{\textwidth}
\addtolength{\La}{-\parindent}
\settowidth{\Lb}{ hyphen}
\addtolength{\La}{-\Lb}
\newcommand{\test}[1]{%
\par\rule{\La}{1pt} #1 \rule{5em}{1pt}.}
\test{hyphenation}
\test{hyphenation\stepcounter{a}}
\test{hyphenation\refstepcounter{a}}
\end{document}
%%
In the third test the word hyphenation is not always hyphenated. In
the following table, you can see the results for different cases:
* without hyperref;
* with hyperref, without option (it loads automatically the dvips
driver with latex, and the pdftex driver with pdflatex);
* with hyperref, with option specifying the driver to use
(i.e. dvips for latex, or pdftex for pdflatex).
In the table, I note correct when the word is hyphenated, and
wrong when it is not.
DVI (latex) PDF (pdflatex)
--
without hyperrefcorrect correct
hyperref, no option wrong wrong
hyperref, with option correct wrong
--
Note that the behavior is correct with hyperref when the dvips
option is given while it is not with the implicit behavior. This is
because the dvips option redefines [EMAIL PROTECTED], while it is not
the case when the default is used:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
}
This particular point may be a Debian (or teTex) specificity: with the
upstream hyperref (as found on CTAN), the default driver is
hypertex.
It is this different behavior with or without [EMAIL PROTECTED] that made
me try to modify this macro.
Furthermore, the bug disappears if we just remove the package hyperref from
entcs.cls .
It disappears too if you modify (or comment) the redefinitions of
\footnote and \footnotemark in entcs.cls.
Arnaud Giersch, in message [EMAIL PROTECTED], found

A very good minimal example!
With \refstepcounter has to set an anchor. On the baseline it looks
poor, thus it is shifted by [EMAIL PROTECTED] This is implemented
by \smash that sets a box. Thus the example can be reduced to
the following plain-TeX file:
\hsize1mm
a hyphenation\par
a hyphenation\hbox{}
\bye
The box prevents the hyphenation.
A penalty cures the prevented hyphenation problem:
\makeatletter
[EMAIL PROTECTED]
\setlength\HyperRaiseLinkLength\HyperRaiseLinkDefault
\HyperRaiseLinkHook
\ifvmode
#1%
\else
[EMAIL PROTECTED]
\smash{\raise\HyperRaiseLinkLength\hbox{#1}}%
\fi
}
\makeatother
But whether it will break other things?
I have added the patch in the next version.
With driver dvips the shifting is done at PostScript level.
In the third test the word hyphenation is not always hyphenated. In
the following table, you can see the results for different cases:
* without hyperref;
* with hyperref, without option (it loads automatically the dvips
driver with latex, and the pdftex driver with pdflatex);
* with hyperref, with option specifying the driver to use
(i.e. dvips for latex, or pdftex for pdflatex).
In the table, I note correct when the word is hyphenated, and
wrong when it is not.
DVI (latex) PDF (pdflatex)
--
without hyperrefcorrect correct
hyperref, no option wrong wrong
hyperref, with option correct wrong
--
Note that the behavior is correct with hyperref when the dvips
option is given while it is not with the implicit behavior. This is
because the dvips option redefines [EMAIL PROTECTED], while it is not
the case when the default is used:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
[EMAIL PROTECTED]
}
Thank you very much, Arnaud, this is indeed a bug and not intended.
It is fixed in the next version.
This particular point may be a Debian (or teTex) specificity: with the
upstream hyperref (as found on CTAN), the default driver is
hypertex.
Because many want to generate PDF files, driver dvips is better.
Thus I introduced a possibility to change the default driver
by a configuration file (hyperref.cfg). Thus the default of
hyperref is still hypertex without pdfTeX and VTeX, but
if hyperref.cfg is used, there another driver can be specified.
Yours sincerely
