Hi Mark,

This works fine for me, in 8.4 and 8.5:

  % set str "a\nb"
  a
  b
  % string length $str
  3
  % string bytelength $str
  3

Are you sure the method you're using to put the string together isn't 
cutting it at the first newline, or something similar? (Can you show us the 
code?)

Regards,
Mike
