I have already covered the topic of font replacement in LibreOffice in 2020 and in 2025.
Unfortunately, the vast majority of personal computer users are unaware of this issue and believe that the fonts installed on their PC are the only fonts available. None of them realise that personal computer fonts are actually software, and as such can be installed on a PC like any other programme, provided that a licence is purchased (in the case of proprietary fonts, supplied by companies such as Adobe and Microsoft) or that the licence is open and free.
Font management is one of the main problems that users encounter when using LibreOffice to manage a document created with a proprietary office suite, because the absence of the original proprietary font (for example, Arial and Times Roman in the case of the older generation, Calibri and Cambria in the case of the intermediate generation, and Aptos in the case of the latest generation) causes the text to flow differently – because the fonts used for replacement are not metrically compatible – and this leads the user to think that LibreOffice is not working.
LibreOffice is the only office suite to provide an input and output font conversion feature which, when used correctly, significantly reduces or even eliminates the problem.
This is because LibreOffice thinks about its users, although it obviously needs curious users who do not stop at a small problem – because a different scrolling on the screen of the same document is a small problem – and instead of immediately thinking that the software is not working, they seek information to find a solution.
In the following slides, which I used for a workshop during the last SFScon in Bolzano, and which I have already published, there is a summary of the problem and its solution. As soon as possible, I will return to the subject with more information, hoping that repetition will help users who do not seek information and who, for this reason, are completely defenceless against the strategies of companies that provide proprietary office suites.
