I'm working on switching the glyph of Eng (U+014A) with the locl feature.
However, I couldn't find a suitable language system tags for Dagbani.
How can I find the right tag?
The information I referred to is:
I plan to use the font I created as a webfont.
For example, in Luganda, HTML lang is "lg". In this case, the OpenType lanugage system tag can use the locl function by specifying "LUG".
However, in Dagbani, HTML lang is "dag". Since the OpenType language system tag in this case is unknown, the locl function cannot be used.
I would be grateful if you could give me some good information.
