Here is a wip module meant to address the issues related to this topic. It is a start with following these rules Line breaking rules in East Asian languages - Wikipedia though it would be good if Defold itself was able to handle these rules on labels/text nodes. Maybe RichText would be a good option for implementing the rules since this is already sort of in its domain.
The wip module can for sure be improved to be more efficient / faster / implement more of the rules by someone who knows how to do those well. 
This image illustrates the kind of problems the WrapText module is meant to address. Because all characters are connected there is no natural white space to allow line breaks. But there are still situations where you don’t want certain characters to be left at the start/end of a line.
