Thats an interesting bug! heres a sorta workaround:
<cfscript>
function Hex7toStr(Char){
var newchar = "";
var asciiChar = "";
var i=0;
for(i=1;i lte len(char);i=i+1){
asciiChar = asciiChar&asc(mid(char,i,1));
}
switch (asciiChar)
{
case asc("0")&asc("0"):
newchar = "NUL";
break;
case asc("0")&asc("A"):
newchar = "LF";
break;
}
return newchar;
}
</cfscript>
<cfoutput>
00:#Hex7toStr("00")#<br>
0A:#Hex7toStr("0A")#<br>
</cfoutput>

Subject: Coldfusion Switch Error - Hex Characters
Hello,
I have an odd error with a piece of code I'm migrating from CF5 to
MX6.1. It is a simple switch statement that takes Hex7 values as a
string and spits out the ascii equivilent as a string.
Problem is, it is reading hex value '00' and '0A' as the same thing,
and returns a duplicate value error for 0.0. I've tried chr codes,
changing it to IF statements, and more. I was hoping an expert could
look at it and give me a hint to a fix. Below is a small snippet of
the overall code. Thanks.
<cfscript>
function Hex7toStr(Char){
switch (Char)
{
case "00":
newchar = "NUL";
break;
case "0A":
newchar = "LF";
break;
case "30":
newchar = "0";
break;
case "41":
newchar = "A";
break;
case "EB":
newchar = "a";
break;
}
return Trim(newchar);
}
</cfscript>
<cfset hexChar1 = "00">
<cfset hexChar2 = "0A">
<cfset hexChar3 = "30">
<cfset hexChar4 = "41">
<cfset hexChar5 = "E1">
<CFSET hexStr1 = #Hex7toStr(hexChar1)#>
<CFSET hexStr2 = #Hex7toStr(hexChar2)#>
<CFSET hexStr3 = #Hex7toStr(hexChar3)#>
<CFSET hexStr4 = #Hex7toStr(hexChar4)#>
<CFSET hexStr5 = #Hex7toStr(hexChar5)#>
<cfoutput>
<table>
<tr><td>#hexChar1#</td><td>#hexStr1#</td></tr>
