Perhaps there is a script at www.cflib.org that would help? I've grabbed
some great scripts from there in the past.

At first glance it looks like Steve's suggestion would break after 50 words
not 50 characters, and Grant's suggestion doesn't take into account whether
the 50th character would break a word.
I would go with Phil's suggestion but process each chunk separately. It's
slower but more accurate (depends on what is more important to you) I.e.
Get the first 50 characters, replace the last space with <br>, then add
whatever came after that space back onto the remaining string and take the
next 50, repeat.
Something like:
<cfset testString = "This will break your text up into lines of no more than
50 chars per line. The quick brown fox jumps over the lazy dog. The quick
brown fox jumps over the lazy dog. The quick brown fox jumps over the lazy
dog. The quick brown fox jumps over the lazy dog."> <cfset formatted = "">
<cfoutput>
testString<br>#testString#<br><br>
formatted<br>#formatted#<br><br>
PROCESSING...<br><br>
</cfoutput>
<cfset space = chr(32)>
<cfloop condition="Len(testString) GT 51">
<cfset Line = Left(testString, 51)>
<cfset testString = Right(testString, Len(testString)-51)>
<cfset Break = Find(space, Reverse(Line))>
<cfif Break GT 1>
<cfset Rest = Right(Line, Break-1)>
<cfelse>
<cfset Rest = "">
</cfif>
<cfset Line = Left(Line, 51-Break)>
<cfset formatted = formatted & Line & "<br>">
<cfset testString = Rest & testString>
</cfloop>
<cfset formatted = formatted & testString> <cfoutput>
testString<br>#testString#<br><br>
formatted<br>#formatted#<br><br>
COMPLETED<br>
</cfoutput>
I haven't looked at how efficient this is though.

If you do that then your looping into every item. Use the step attribute
then you processing will be a lot quicker aswell

crap i wasn't finished
<cfset insertpoint = 50>
<cfloop on the String>
<cfset string = insert("<br>", String, insertpoint)>
<cfset insertpoint = insertpoint + 50> </cfloop>
