Convert copyright symbol to string "Copyright"

Using xsl version 1.0 I am trying to convert a copyright symbol to the text
string "Copyright". I tried doing a       <xsl:value-of select="translate(.,
copyrightsymbol, 'C')"/> which works great, but can't make the translate
more than 1 char. Have looked all over the place for a solution but haven't
had much luck. Do I have to search each character in text see if it matches
the symbol and then replace it or is there a simpler method like above?

Any help and samples will of course be greatly appreciated

Thanks,

Dan Whitney
