utf-8 to hexadecimal

I have tried hexToString function but does not display characters correctly.

For example, I used the code from cf.marc to convert an Asian character to hex (value is 4e2d).

After using hexToString, the character is not correctly.

Pls kindly advise.

Hi,

You can try this UDF.

http://cflib.org/udf/hexToString

Thank you very much.

Pls kindly also advise how to convert hex back to utf8.

<cfif structKeyExists(form,"asian_string")>
<cfset strLen = len(form['asian_string'])>
<cfset hex = arrayNew(1)>

<cfloop from="1" to="#strLen#" index="i">
<cfset current_char = mid(form['asian_string'],i,1)>
<cfset arrayAppend(hex,formatBaseN(asc(current_char),16))>
</cfloop>

<cfdump var="#hex#">
</cfif>

<form action="" method="post">
<input type="text" name="asian_string" />
<input type="submit" />
</form>
