I'm currently working with vim a lot. (Not on my own  system  but
on  other  ones and in not so sane environments.) Vim's s-command
can work on newlines, but one needs to know about the quirks:

     In the syntax s/foo/bar \r and \n have different meanings,
     depending on context.

     For foo:
     \n = newline
     \r = CR (carriage return = Ctrl-M = ^M)

     For bar:
     \r = newline
     \n = null byte (0x00).

I work with Unicode stuff, currently.

There is this useful website to get information on  Unicode  code
points.  [1]

The most basic knowledge on Unicode is taught by Joel.  [2] (He's
wrong  in  one  point:  `ß' is no strange way to draw `ss', but a
quite straight forward ligature for `sz', with the old `long-s'.)

Iconv(1) can be used to transcode text. It's error  messages  are
sometimes  missleading. Not every ``illegal input sequence'' is a
problem of the input, but rather a problem of  the  output.   ;-)
Quite  revealing!   [3]  To  solve  this  problem,  one  can  add
``//TRANSLIT''  to  the  target charset to get illegal characters
replaced by ``similar'' ones:

     iconv -f utf-8 -t latin1//TRANSLIT



I don't like that in mysql I need  to  write  down  passwords  in
clear  text.  They get stored in the command history and some guy
behinde me can watch me writing ... Hmm. :-( It's nice  that  the
whole  user  management of mysql is done in mysql itself, but the
passwords are a problem.
