Bingo!
Shavian is custom to English and also featural (quite smart), but it has no connection to history. People like to have that rootedness whether they know it or not. Although, I suppose Hangul took off without a history as well. But if the king of england required adoption of shavian, that would also be quite the historic event
Regarding the issue of accents and mergers, I think it is natural that there will be different âofficialâ dictionaries for different major accents. I donât see it as a problem as long as the letter sounds are agreed upon across accents. Keyman has a wonderful prediction system for keyboard too so you can include your preferred dictionary for your accent.
Great comment with great ideas!! I also would find it tragic if some runes were simply unused. So many of them are beautiful.
