I have a online form which require user to input text (which may contains asian language). the charset of the application is utf-8

How could we convert the received text into their hexadecimal values?

pls kindly advise

<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>

Hi,

You can try this UDF.

why?

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.
