Hi Marc<br><br>I have the problem with unbalanced parentheses when use cl-pdf library (in revision 159).<br>This problem is solved in the cl-typesetting library (stroke.lisp):<br> (when (find char "\\()" :test #'char=)<br>

The problem is in the cl-pdf library and should be resolved there.<br><br><br><div><span class="gmail_quote">2008/1/20, Marc Battyani <<a href="mailto:marc.battyani@fractalconcept.com">marc.battyani@fractalconcept.com</a>>:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
