Let's search if "Greek" is supported. It is, because I can see "Creek"? Creek is not Greek, it is the language/script of an American Indian tribe. Then, the list is too long to find a specific language.
What should have happened, is to add in the document an extra paragraph that reads like this:
> This font currently supports the Latin-based Unicode character ranges. See below the full list of language support.

To meet the needs of global communication, Recursive supports a wide range of Latin-based languages, including Vietnamese. It also comes with an extended set of currencies, symbols, fractions, and arrows.
I do not think this has been a last-minute addition. I read the paragraph again, and I found it difficult to quickly scan the text that is presented in that font. The letters appear to me (Linux/X11) as too thin and faint.
Does anyone else have this issue?
