Thanks! But it should be \xa0. First I tried matching with regular
expressions and that worked using . (dot) for the unknown character. I
then found this page about
<http://www.w3.org/International/questions/qa-escapes> where it says:
"An example of an ambiguous character is 00A0: NO-BREAK SPACE. This type
of space prevents line breaking, but it looks just like any other space
when used as a character. Using (or  ) makes it quite clear
where such spaces appear in the text.".
So this works:
$agent->follow_link(text => "Edit\xa0Librarians", n => 1);
