Improve the line break logic of text boxes.

[ZYJYGE]

At present, in text boxes(like Action Description), the newline logic of text is based on the recognition of spaces between words. However, for some other languages (such as Chinese), spaces may not be used in their language systems, which leads to the program believing that the entire paragraph is a single word, resulting in some multilingual processing problems.
