The second picture works. The first picture produces quite an error message
(below). I’m using

Any help would be greatly appreciated!

You started a keyword but it seems to be an invalid one. The first character(s)
might give you a clue. You might want to quit unwanted lookahead with \relax.

Re: [NTG-context] Off topic: Does a 'free for commercial use' flared-sans font exist in the world?

It is the best community. And I tell you what. What happened is that all TeX engines have neglected fonts from the beginning. Really? When tex showed up digital font technology was pretty much in flux. And, with metafont being part of the tex ecosystem, one can argue that tex was quite innovative too. Potscript and its fonts came aroudn at the same time and were rather closed technologies. But as soon possible backend drivers (also part of the tex ecosystem) kicked in. Then we got virtual fonts which enhanced tex's capabilities. I really like Optima, and what I really like about it is the 'flared style'. But I would like to move to a flared-sans font that gives me more licensing freedom. I haven't been able to find one after extensive searching. The only one who were reasonably priced (not free) were the URW Classico ones in Adobe Creative Cloud, but those can only be used in Adobe programs like InDesign (and not TeX). Licensing freedom is an oxymoron. There's no freedom in licensing. Only greed. The only extension engine that at one point had a plan in mind, or most of the bases covered in this regard was Omega. One needs morr than plans. Afaik omega was more about input processing and th efont part was mostly going beyond 8 bit fonts but i might have missed something (omega was never productin ready). It is xetex that hooked into opentype although pdftex can actually deal with truetype fonts to some extend. Before there was something 'opentype' we had two competing but similar technologies. And it took a while before it was even clear how to interpre the specification (also think about reverse engeneering fonts and heuristics and ... bugs or features ...). TeX was always pretty fast in picking up new stuff (maybe users less so). When it came to commercial fonts the plan of action ahead was by including PFC data on these very same commercial fonts that would benefit primarily its opentype versions in the long run. What is PFC data? What do you have right now? Opentype fonts only. Sure. Quality can be even the same than its type1 counterpart, and at times not so much according so some folks that have bothered to go the extra length in making the most accurate comparison that's available between them two. For most fonts it's just 'more shapes' which then also leads to more ligatures, kerns etc btu that is already nice. And when fonts lack something we can always tweak them (runtime). But looking at it from a bright side/perspective, I think we're no longer facing the same pre-historic constraints of including a font as before, as long as it's not for commercial purposes, You are well aware of these non and commercial uses even before your extensive search anyway, I'm not sure what is the difference between commercial fonts and free ones as they use the same technology; with some exceptions, fonts are not that expensive (take lucida from tug, making fonts takes time after all); and for publishers it's noise on their budgets. p.s many many years ago I read and followed some publications about the aformentioned extension and just went over them recently, to have an idea what did and did not work. In regards to typefaces, its goal was unmatched, or so I think. It might be comforting to know that right from the start luatex made a lot possible wrt fonts (runtime manipulation) and was also one of the first to support variable fonts, color fonts etc (not that many care about that). And with luametatex we go even further. I found some flared-sans fonts, but not one with at least regular, italic, bold, and bold-italic. Is there really not a single flared-sans font that is really free (so also for commercial use) to use out there? I had to search the net to figure out that flare sans fonts are sans fonts with serifs For those into fonts: https://tug.org/TUGboat/tb44-1/tb136carter-romano.pdf I a very nice overview of how it went with digital fonts (and what we probably lost in getting where we are now and might loose soon).
