Convert ’ to an apostrophe

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.
