Payment Amount Text in eText template for check printing

Summary:

We have a requirement to print check amount in below format

ONE THOUSAND FIVE HUNDRED USD AND 00/100 DOLLARS

Currently xml generated from PPR is having format like this

ONE THOUSAND FIVE HUNDRED USD AND ZERO CENTS***

Content (required):

We need to check if a word is complete or not in a line if not complete fill it with '*' and push it to next line. For example, 'FOU' could fit in first 38 characters but as it is incomplete it should fill with * and move to next line. Appreciate your help on buidling this logic.

This has to be built in eTEXT.
