There is one missing piece to the puzzle.  This is what happens behind 
the scenes when you convert from a string written in UTF-8 format to a 
string written in ISO-8859-15 format:

UTF-8 encoded character
    |
    |
    V
Unicode integer
    |
    |
    V
ISO-8859-15 encoded character


If for some reason, you ever need to get the unicode integer, you can do 
this:

str = "\xc3\xb6"  #'o' with umlaut encoded in utf-8
arr = str.unpack('U')  #'U' gets the unicode from a char encoded in 
*utf-8*  only

p arr  #[246] --> unicode in decimal format

Since unicode integers are usually written in hex format, you can do the 
following to get the unicode in hex format:

puts "%04x" % arr[0]   #00f6
