Here is the B4A StringFunctions library, converted to B4J. This is a Beta version and I am looking for feedback and testing. I don't expect all this will be working this first try. I just started in B4J a few days ago. The one known issue is the MB() function will not work but there may be others as well. Any feedback or help testing would be great. See the B4A StringFunctions Library in my signature for the docs.
