=head1 NAME

latexout.pl - Filters the LaTeX log and output, so that UTF8 stays UTF8.

=head1 SYNOPSIS

latex I<arguments> | latexout.pl

=head1 DESCRIPTION

TeX replaces bytes in the range of 0x80 to 0x9F by ^^xx
sequences. This filter restores them.

=head1 BUGS

Only complete lines are parsed, so when TeX wants input, the prompt is
not displayed.
