This should be 
  result = perl.substitute( "s/\\b/\t/", input);

The regular expression escapes will be interpreted by Perl5Compiler,
but the substitution is handled by Perl5Substitution.  So escapes
in the substitution should be straight Java, except for \u\U\e\E which
where added by Mark Murphy to handle inline case modification, which 
although technically part of Perl string handling, was deemed of
sufficient importance/convenience.

I am not sure I understand your response.  Let's ignore \a, \b, \e and
\v for now.  How does substitute() parse the input string?
