I don't think stuff about non-English character sets is very relevant here, since internationalization is part of the standard Linux base and available in all distros.  Perhaps whether language can be selected at install time is relevant, but since Tony, I think, mentioned that UK is Ukraine and not GB, or was that another podcast, these installers are both likely to include localization.

I can't commit to joining anybody for a podcast, but I could offer a goodly amount of guidance as to what we, meaning blind people, need to know.

Of course VI is just one aspect of accessibility.  Consider also people with limited or impaired fine motor control, or missing hands etc.

At the very least, I want to know one thing immediately with every distro...can I install it alone, IOW with no help from a light-slave.  If the answer is no, not interested.

Windows 10 can now be installed by me, thanks to Narrator now being an excellent screen reader.  But then accessibility on Windows leaves Linux dead. Just one of the ways in which Windows, IOS, and Mac OS are all superior
