Asian characters in newer powerpoint not converting


if i save a powerpoint presentation in the 2007-2013 format (.pptx), GroupDocs will not convert to .pdf any text field that has some asian characters in it (see asian characters 1.pptx), but if i save the exact same document in the 97-2003 format (.ppt), the conversion happens just fine (see asian characters 1.ppt).

i’m using groupdocs for java version 17.7.1




Thank you for your inquiry.
We couldn’t reproduce this issue using the problematic files you shared and 17.7.1 version of the API. Please find the output of both files below:

For further investigation, we’d require sample project and problematic output file from you.


thanks Atir!

i was not able to duplicate the problem running on MacOS. i WAS able to duplicate the problem with the following OS and Java runtime:

OS: Ubuntu 14.04.5 LTS, Trusty Tahr
Java: java version “1.8.0_161” , Java™ SE Runtime Environment (build 1.8.0_161-b12) , Java HotSpot™ 64-Bit Server VM (build 25.161-b12, mixed mode)

as i mentioned in the OP, i can only get it to fail with the newer version of PowerPoint format, not the older version.
