[CONFSERVER-39441] File Preview Macro Showing Garbled Characters for Office Documents Containing Certain Special Characters
We got this issue in 7.3.5 as well,
Any solution is future release ?
We are experiencing this issue after upgrading to 7.3.1. This was working fine in 6.13.0.
My ppt doesn't have any special characters. It shows garbled text for regular text when previewing ppt
Is there an update to this ticket? We are running 7.2.2 and we are impacted by this bug. It would be nice to have it fixed. Thanks
Hi,
We have the same problem with danish characters ø, æ and å.
We just get blanks.
Running Confluence 6.15.4
Hello everyone,
We are also having this issue specifically when previewing pptx. Has anyone tried the workaround provided in this ticket and did it worked? Thanks.
We are in Confluence 7.1.1.
Hi Everyone,
Have we tried the resolutions provided from the following documentation:
Kind Regards,

We are closing this ticket as we believe a fix is available for most customers experiencing this issue in Confluence 7.10+. This issue can actually be broken down into few separate issues.
1. Garbled single byte Western characters on Linux
We believe this was resolved with Linux installer changes in Confluence 7.10 that install missing fonts when Confluence is installed. If you are still experiencing this issue after upgrading to Confluence 7.10, please raise a support ticket and include details of your OS name, OS version and include a sample file and we’ll look into it.
2. Garbled multi-byte CJK characters on Linux
This should be partially fixed since 7.10 if Confluence is installed through the Linux installer. We upgraded the libraries used for Office document processing in 7.10 and improved the Linux installer script to install some fallback fonts which improves Confluence compatibility with Office documents with certain CJK fonts on Linux, especially CentOS. There are some edge cases the libraries cannot support for now. If you experience that on Confluence 7.10+, please contact support and include a sample file and specify your OS name and version when raising new issues, so that we could investigate further. It is also worth noting that as far as we have seen, this issue does not occur when Confluence is running on a Windows server. If you are interested in the remaining edge cases for garbled CJK characters please watch https://jira.atlassian.com/browse/CONFSERVER-61040 instead.
