--- Comment #7 from Nicolas Mailhot nicolas.mailhot@laposte.net --- Tahoma and other parts of Microsoft’s “fonts for the web” are very early display fonts with lots of technical mistakes.
So, they are challenging to display correctly, because they are, basically, incorrect (they were built around the bugs of the Windows text engine, and the screen pixel resolutions, of the time, both of which do not apply on a 2019 Linux system).
The version Microsoft ships in Windows has been fixed a long time ago (or they may special-case it, I don’t remember).
The version people keep installing on Linux is the same 1990’s Microsoft dump. Because they do not have access to the fixed font files for legal reasons.
