Convert †to an apostrophe

Question

From an XML , the curly apostrophe is rendered as : ’, and displayed as ? (unknown)
because my server and Cf are in ISO--8859-1.
As this is an included file,
I cannot use the tags :
<cfprocessingdirective pageEncoding="UTF-8">
<cfcontent type="text/html; charset=UTF-8">
I only needs it for a small piece of text dipslayed. Not the whole page.
I searched for hours, I did not find any solution to convert the ’ to a single apostrophe.
I tried :
<cfset title=#replacenocase(title,'’',"'","all")#>  does not do anything.
I tried :
<cfscript>
          s="#title#";
          chr_current="UTF-8";
          chr_new="ISO-8859-1";
          c=createobject("java", "java.lang.String").init(s);
          convstring=createobject("java", "java.lang.String").init(c.getbytes(chr_current),chr_new).tostring();
          title=convstring;
</cfscript>  does not do anything.
I tried :
<cfset title=#replacenocase(title,"’","'","all")#> does not do anything. Because the char found is : ’
Thanks for any help.
More general question is :
How to convert a piece of text from UTF-8  to  ISO--8859-1 ?   not the whole page, because text coming from the DB is
stored as  ISO--8859-1.

Answer 1

As I cannot update my question above, I add this : the original code from the XML code is :
<title><![CDATA[Sven Yrvind : un ketch de 15 pieds à travers l’Atlantique !]]></title>
If I take only : title=Sven Yrvind : un ketch de 15 pieds à travers l’AtlantiqueÂ
and use : <cfset title=#replacenocase(title,'’',"'","all")#>
Then it does work.
The <![CDATA[   make this replacement not working.
Thanks for any Help .
