hey.  
how would i convert a letter to its corresponding utf integer and back to a letter?  
Trying to do a real simple rot encryption  
[AS]  
private function decrypt(line) {  
var line = line.split("");  
trace(line);  
for (var zz:int = 0; zz \< line.length; zz++) {  
line[zz] = ConvertToUTF(ConvertToInt(line[zz]) - offset) ;  
}  
trace(line);  
}  
[/AS]  
ConvertToUTF(); should take in a number and convert it to its corresponding letter  
ConvertToInt(); should take in a letter and convert it to its corresponding int

Thanks!

P.S. im not sure that its called utf, but i mean how every letter corresponds to an integer.  
in java i would do like this

```auto
 e[x] = (char) ((int) e[x] - encryptionOffset);

```
