Description: ------------ In the LaTeX render classes for both wikilink and freelink (and most likely others) variable substitution is used to insert the values into the formatted string. This is unsafe as it inserts an extra \ which masks a { and latex cannot match the next } correctly. A more correct (or at least safer) version should use concatination to build the return string. Affects (at least): Render/Latex/Wikilink.php Render/Latex/Freelink.php Test script: --------------- $text = 'foobar'; $href = 'http://www.example.com/wiki?id=foobar'; return "$text\\footnote\{$href}"; A safer version: return $text. '\\footnote{'. $href. '}'; Expected result: ---------------- foobar\footnote{http://www.example.com/wiki?id=foobar} Actual result: -------------- foobar\footnote\{http://www.example.com/wiki?id=foobar}
