"Swahili as used in the Democratic Republic of the Congo (cd)" seems to have an own language code: swc per https://en.wikipedia.org/wiki/Congo_Swahili

Can you confirm that "swc" would be a better code than "sw-arab-cd". Or "swc-arab"?

I am unsure and ask @Amire80 for help. I do not want to introduce codes that are wrong or very unsual.

There are also wmw and ymk, which may work for Mozambique, but I don't actually know which ones to use.

Luckily, we have @jhsoby in the Language committee, and he happens to know some things about Swahili. Perhaps he can help better than I can?

On the Swahili documents in Arabic script from the Congo (19th century):
https://d-nb.info/123807765X/34

pg. 23 “It seems that all the Congolese Swahili documents were written in Kiunguja, the Swahili spoken in Zanzibar. None of the documents show any trace of Kingwana – the variety of Swahili which was progressively used as a lingua franca between the traders, the local population and the Europeans in parts of the Congo. This sounds quite logical, since the authors of these documents all came from Zanzibar or settlements like Ujiji and Tabora which had been founded by Zanzibari merchants. The use of Kiunguja in the Muslim Swahili community of the Congo seems to have persisted afterwards. In 1956, Harries reported that there was a big difference between Kingwana, spoken as a lingua franca by the Congolese indigenous populations, and the Swahili spoken by the Muslim population of Swahili descent, which was very close to Standard East African Swahili (Harries 1956: 396).”

It seems like the code swc is intended for Kingwana/Kitanga Swahili, which has major differences from standard Swahili. However with these code requests I am intending to use them for what is described in the quote above, standard/Zanzibari Swahili as used in the Congo.
