From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Those fonts are not free. They may be just ttf files, but there is a massive amount of work that goes into creating a font with unicode support. If you just want fonts for basic compatibility, you can use open source fonts with compatible metrics such as the Liberation fonts or use the microsoft core fonts that haven't been updated in 20 years.
Yes I know. But I mean microsoft will not get poor if we share their proprietary fonts they set as default on all documents.
Btw how are fonts integrated in PDFs? You can load the documents without the fonts installed
Many fonts have a license that allows them to be embedded in a pdf. Newer fonts usually have a flag that tells the software if the font can be embedded or not, not all software respects that flag though. Older fonts don't have the flag and will embed even if you are not allowed to embed them.
Thanks for the info! So the entire .ttf package is embedded, or every single character as SVG? Damn that sounds like a waste of space compared to HTML where fonts with alternatives and fallback also work.
Typically, only the glyphs for the characters used in the PDF are embedded.
