Understanding language choices in software
I'm working on a passion project, tentatively called "Barriers of Babel: How Languages and Accessibility Intersect." Today I had a minor breakthrough. I had spent a few days trying to understand which human languages Windows and Android support. I thought it was a matter of matching the language name, and sometimes the region and script, to the IANA language subtags . Then I looked at the NVDA screen reader.
