Nederlands/Dutch language support

[jonbuffington]

Thanks for making this font available!

I installed JetBrainsMono and noticed that Nederlands/Dutch is not a supported language on macOS 10.15.2. Is that an oversight/bug or is support more complicated?

Here are the languages reported in Font Book.app:

Afaan Oromo, Afrikaans, Albanees, Asu, Baskisch, Bemba, Bena, Bosnisch, Bulgaars, Catalaans, Cebuano, Chiga, Cornish, Corsicaans, Deens, Duits, Embu, Engels, Erzja, Esperanto, Estisch, Faeröers, Filipijns, Fins, Frans, Friulisch, Galicisch, Gikuyu, Groenlands, Gusii, Hongaars, Ido, Iers, IJslands, Inari-Samisch, Indonesisch, Interlingua, Italiaans, Javaans, Jju, Jola-Fonyi, Kaapverdisch Creools, Kalenjin, Kamba, Kinyarwanda, Kirundi, Koerdisch, Kölsch, Kroatisch, Lets, Litouws, Lojban, Luganda, Luo, Luxemburgs, Luyia, Macedonisch, Machame, Makhuwa-Meetto, Makonde, Malagassisch, Maleis, Maltees, Manx, Maori, Meru, Morisyen, Nedersaksisch, Nedersorbisch, Noord-Ndebele, Noord-Samisch, Noord-Sotho, Noors - Bokmål, Noors - Nynorsk, Nyanja, Nyankole, Occitaans, Oppersorbisch, Pools, Portugees, Reto-Romaans, Roemeens, Rombo, Russisch, Rwa, Samburu, Sango, Sangu, Sardijns, Schots-Gaelisch, Sena, Servisch, Shambala, Shona, Sloveens, Slowaaks, Soga, Somalisch, Spaans, Swahili, Swazi, Taita, Taroko, Teso, Tsjechisch, Tsonga, Tswana, Turkmeens, Vunjo, Waals, Walser, Wit-Russisch, Wolof, Xhosa, Zoeloe, Zuid-Ndbele, Zuid-Sotho, Zweeds, Zwitserduits

Hi @jonbuffington did you try to type text in Dutch language? I believe the JetBrains Mono have all required symbols to support it. If it isn't so, we will add them in one of the next updates.

I do not think the issue is missing glyphs. I suspect it as simple as adding Nederlands to the slng attribute in the font metadata. It may be just an simple option to set in the FontLab/application that generates the the ttf files.

Here is a reference I found to the slng tag read by macOS to determine whether to display the Font in an app: https://docs.microsoft.com/en-us/typography/opentype/spec/meta

Looks like we still need more glyphs. Closing this issue because it's duplicated. #100
