I had to undo the replacements of character encodings which the scripts performs, e.g. replace "-" back to "& # 8 2 1 1 ;". However, this may be handled in the same manner as in this python script, i.e. replace line 79 with

my $currentDocString = $currentDoc->toString;
$_ =~ s/([a-zA-Z])-([a-z])/$1$2/g;
$currentDoc =~ s/ / /g; #no-break space
$currentDoc =~ s/ᵉ/ᵉ/g;
$currentDoc =~ s/‑/‑/g; #non-breaking hyphen
$currentDoc =~ s/–/–/g; #en dash
$currentDoc =~ s/—/—/g; #em dash
$currentDoc =~ s/ / /g;#narrow no-break space
print $xmlFileHandle $currentDocString;

This code is not yet tested and especially the regexp might need some unescaping. Moreover, it is critical here, that not too much of the xml is replaced (don't we have to restrict to attribute-values??).
