Count number bytes in UTF-8 for Java String

https://bitbucket.org/bugs_/utils/src/default/CoreUtils/src/main/java/cz/vondr/coreutils/utf/Utf8LengthUtil.java

• Problem 1: You have Java String variable. And you need get number of bytes in UTF-8
• Problem 2: You need split String into multiple Strings, in the way that each of them have exact number of bytes. (expect last part of course :) )
