I ran into the same problem as mentioned in this thread:

However, I don't know if you monitor old threads so I thought I'd drop a breadcrumb here.
I am willing to provide the source if you want it.
Hello,
Thank you for your post. I have been looking into it and I can say that if the string contains different words, the default behavior is to carry the whole word to the new line, not just a letter from it. Please let me know if this helps you or I have misunderstood your question in some way.
Looking forward for your reply.
