History

ColdFusion MX: Changed Unicode support: ColdFusion supports the Java UCS-2 
representation of Unicode character values 0–65535. (ColdFusion 5 and earlier releases supported 
ASCII values 1–255. When calculating a length, some string-processing functions processed the 
ASCII 0 (NUL) character, but did not process subsequent characters of the string.) 

Parameters

Example

<cfif IsDefined("Form.MyText")>

<!--- If len returns 0 (zero), then show error message. --->
<cfif Len(FORM.myText)>

<cfoutput><p>Your string, <strong>"#FORM.myText#"</strong>,
has <strong>#Len(FORM.myText)#</strong> characters.</cfoutput>

<cfelse>

<p style="color: red; font-weight: bold">Please enter a string of more
than 0 characters.</p>

</cfif>

</cfif>

<form action = "<cfoutput>#CGI.SCRIPT_NAME#</cfoutput>" method="POST">
<p>Type in some text to see the length of your string.</p>

<input type = "Text" name = "MyText"><br />
<input type = "Submit" name="Submit" value = "Count characters"><br>
</form>

Parameter

Description
