Quickly looking at <http://www.w3.org/TR/xhtml1/>, it looks like you can
create new entities for referencing particular characters (e.g. you can
make your own &registered; to refer to the character used to represent
&reg;), but it doesn't seem to suggest that you can use it for a whole
string of characters.

Non-XHTML alternative solutions:  

Search and replace in your text editor, if it's for a once off authoring
solution.

SSI for webpages that might need their variables updated.  I do that for
my price lists.  One "include" source gets updated, and any page that
refers to some particular item's price shows the current one.
