Mostly people never change the value of  \UTFencname
from its default of
    EU1 (if  fontspec  is loaded first)
or U  if xunicode.sty  is loaded first.
So if you never change  \UTFencname  then it doesn't
matter whether you use the macro or its value.


But there is nothing stopping you from using other values.
e.g.
      \newcommand{\UTFencname}{bubbles}
      \usepackage{xunicode}

will make all the same definitions work in "bubbles" encoding.


Also, you can read-in the file  xunicode.sty  more than once.
e.g.

   \newcommand{\UTFencname}{U2}
   \usepackage{xunicode}
   \UndeclareUTFcomposite[U2]....
   \UndeclareTFcharacter[U2]....
    ...

   \usepackage{fontspec}
   \newcommand{\UTFencname}{U6}
   \InputIfFileExists{xunicode.sty}{}{}

allows you to setup different encodings supporting
different subsets of characters; e.g. for use with
different fonts according to what they do/not support.


I believe that this ability is very useful for the
discussion that started this thread.
