I am new to POI. when I merge more than one docx with same fontFamily (Airal, Calibri, Times New Roman), there is no issue on combined docx. For example, If I have two docx with the same Calibri fontFamily, there is no issue on combined docx. It keeps and comes out with original formatting. However, merging different docx with different fontFaimly messed up. For example, if I more then one docx, Airal, Calibri, it doesn’t keep the original formatting. especially second docx. First one is okay on combined docx 1 – what am I doing wrong and how can I prevent that from happening?
