To guarantee an accurate display of Word documents when the SECollab server is installed on a Linux system, it is recommended that users include fonts in the Word documents that they wish to publish (enabled by default). If for some reason this option cannot be preserved, it is necessary to install the most common Windows fonts on the Linux server. If your company uses specific fonts for its documents, those should be installed as well.
To know how to install fonts on your Linux environment, please refer to its documentation.
