Chinese and English

As the attachment shows ,the style is not good because Writer automatically begin a new line from the middle of the first line。 At the end of the first line the blank is too long。But in MSOFFICE this problem is settlled by corret settings。
I tried  almost every version of Lireoffice and found the  same result。On Windows and linux the result is same.

The all substance of the attachment is "由于该厂区新建,部分厂区还没有建好,目前应用的信息化系统还较少,只有PDM、DNC,CAPP、ERP、MES系统暂时没有。从发展趋势来看,该厂会在近几年实施这些信息化系统,因为该厂的资金情况较好,且领导对信息化比较重视。 "

This is still an issue in 5.3 - Phrases separated by full-width comma or full-width dot are treated as one single word, hence it is put to the next line.

Correction:

In [1] we detect the language of the last portion to determine the locale for the break iterator. The document under test has "en_US" there and the Unicode break iterator found the incorrect word boundary.

There are few issues:
1. The heuristic rule is wrong in this case.
2. Unicode break iterator didn't break before ideographic punctuation.
3. The word breaking algorithm in UAX29[2] should work for us. Why do we need break iterators for three scripts?
