Not a supported font format or standard PDF font. about fontkit HOT 5 CLOSED

ttc is not a single font but an OpenType font collection, containing multiple individual fonts packed into a single sort-of-archive format. As browsers and many PDF tools don't support collections, unpack the .ttc to individual .ttf or .otf files (depending on which OpenType flavour they are) and then use those individual fonts, instead.

Unpack into a single file could be a solution if I knew how.. However it was perfectly working before.. I believe it's a bug that is making a if statement somewhere down in the core code fails when it compares string === buffer... Maybe it's just a matter of doing something like string === buffer.toString().. Which I will investigate further next week when I get time..

ah I see. In the mean time, there are a few solutions to unpacking a .ttc, the one that's the most "guaranteed to do the right thing" is to use FontForge, load the collection, and then file -> generate new fonts from the set that loads in. There are some conversion utilities and online converters, but as the de facto libre Font editor for decades now, FontForge is pretty reliable (and you can even automate the task with something like https://gist.github.com/fatum12/941a10f31ac1ad48ccbc)

It is a buffer probably because it is encoded in an encoding that isn't supported out of the box by node. If you install iconv-lite alongside fontkit, many more encodings are supported.

i think that would be the reason.. i might had some other non related dependences to fontkit that was briging along some "extras" that fontkit was making use of... after deleting them (and many others) i have no idea which one had the piece needed to fix this puzzle... still i feel it shouldnt return a buffer when it clearly says it returns a string on the docs?(forgot where i saw it, maybe the source?).. maybe throw an error when it happens? anyway i have solved my problem by doing as pomax said... converting .ttc to .ttf with FontForge.
