Have you tried the simpler approach of escaping all characters with
unicode equivalents?

If that doesn't suit your needs, maybe something like this (untested):
<cfscript>
emailaddr="[EMAIL PROTECTED]";
initlen=len(emailaddr);
maskedemailaddr="";
for(i=1; i lte initlen; i=i+1){
thischar=left(emailaddr,1);
if(thischar neq ".")){thisimage=thischar;}else{thisimage="period";}
maskedemailaddr=maskedemailaddr&'<img src=""> emailaddr=right(emailaddr,(len(emailaddr)-1));
}
writeoutput(maskedemailaddr);
</cfscript>
Not sure what other characters besides periods are illegal as file
names...
Store 'maskedemailaddr' in your database (if you are using one) so
you're not running this code per page request. Variable scopes would
speed things up if running this per request.
