Provide TTF
Word has issues when exported documents with OTF typefaces in PDF format (they don't get embedded). Would it be possible to also ship TTF in addition to the OTF files?
Why should the burden for problems like this fall to an open source project like this to work around what is clearly a bug in expensive commercial software? Did you report this to Microsoft?
Too much effort to do and maintain (and needing to handle the difference in rendering between TTF and OTF, differences in hinting strategies, and so on). So much effort to work around a limitation in MS Office. Not to mention user confusion on which version to use and download.
There are several alternative “PDF printers” for Windows that you can use to work around this.
I'm going to re-open this for review. Frankly I could care less if Word support. Given the level of control they maintain over the file format spec in the first place the fact that Microsoft of all people doesn't fix long standing bugs in their OpenType implementations in their flagship products just rubs me the wrong way. However there are a couple more reasons the extra work required to ship TTF versions may be worth it.
-
One is that if (and this is a big if, but it's a consideration) Libertinus is going to get listed on Google Fonts (see https://github.com/google/fonts/issues/12) then it would need to have a working TTF build pipeline because that's the format their, QA, build, and delivery pipeline requires.
-
There are some platforms and rasterization situations for which the hinting options available for TTF files may be preferable to those available for OTF.
At the end of the day it seems like OTF should still be our primary deliverable and somehow this would need to be documented to reduce confusion; but it might be worth the effort to review the hinting settings and add TTF as an alternative output format.
I had the same problem as "musm". What resolved the issue for me, was using an online converter like "Convertio", converting the otf - files to ttf, and then installing the latter. Word embeds the ttf- files without any problems.
Typst has requested TTF support. While their reasons for needing it are dubious (their OTF subsetter is not fully functional) it might be possible to supply something that works for them easier that it would be to supply something that works for Desktop apps in general since the hinting story is completely different in PDFs.
Our reasons are indeed dubious (bad subsetting and printer issues we had with OTF fonts in the past), so it's not on you to provide TTF support. I was just wondering whether TTF are available because it would allow use to switch to Libertinus earlier rather than waiting until those problems are resolved.
