Hello.
MS provides a converter to open the hwp file in word. (https://www.microsoft.com/en-us/download/details.aspx?id=49152)
When I looked at the hwp file through the function to test it, the xml parsing error was printed as follows.
Accordingly, when I checked the cause through the xml file in the docx file,
if the hwp file font name includes '&'
It was confirmed that parsing error came out due to the '&' character.
When I replaced the '&' character to '&' and save file, I confirmed that the file was opened without any problems. (change all of the '&' (document.xml / footer1.xml / header1.xml / footnotes.xml / endnotes.xml )
This converter is provided by MS.
I want to know if MS can fix the error.
