Can't import files with emoji with Office importer

Hi! On my side I've tested on XWiki 17.4.5 and on 16.10.11 using LibreOffice 25.2.5 with the original .docx file (52 pages) by importing it with "Create > Page from Office" and by importing the file using "Import Office File" from CKEditor and it seems I couldn't reproduce the issue, the file was imported successfully and the emojis are displayed on the imported page.

Maybe the issue reproduces on certain conditions only or there is a change between the LibreOffice versions.
