How to count characters in a text field on WD4A MBO sheet

$

Hi experts,

 

I got a requirement from customer who is using MBO sheet on WD4A.

 

They have some text fields in the sheet, in which maximum characters are set.

They really hate the system warns about maximum characters when they try to save the sheet.

They want to see how many characters they already put in the text field in realtime manner.

(I think they want it like the way Amazon.com does in thier gift message input field)

 

If it's not possible they can compromise with a calculate button and popup windows which tell them the current number of characters.

 

They want us to do whatever it takes, add-on or modify,  to get this done.

 

Does anyone have any idea to implement this requirement?

 

Thank you for your help in advance.

Best Regards,

Naofumi
