>>45411825indeed, they should be expanded to greek, cyrilic(just the russian set would be nice), hiragana, katakana, "&", @, and obscure letters like Ŋ(eng, as in siŋ(sing)), Þ(thorn, the cursive for of this letter looked like Y, so italian typesetters that did not have a Þ used Y with a tiny e on top as a substitute, this is where the people of now got the misconception that its "ye old whatever", went it has always been "þe old whatever"), Ø, Æ, Œ, ſ(long s), ẞ, Ä, Ü, Ö, ð(eth, and in "that", where Þ is "this"), Ᵹ(insular g, other insular letters might be nice as well), Ȝ(yogh, interesting story), Ƿ(wynn, the contender that lost the battle against W for the sound), Ꝩ(vend, wynn's partner but for the V sound(and also U, and even W sometimes, early english, i tell you...)), (tironian et), Ñ, Ç, the upside down ? and ! from spain(¿¡), the percontation mark ⸮ and finally the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, ↊ and ↋(perhaps even the tonal numerals(early hex before computer were a thing), but with a slightly altered ordering to take into account the current use of numbers also taking into account the two dozenal numbers(rotated 2 and rotated 3, if you have a font that covers them), is easy the tonal order currently is 012345678A("A" is nine)9(9 is ten, the guy designed it for an analogue clock face and wanted mirror symmetry)BCD(D is a rotated 3)E(E is a rotated 2)F, it just needs to be changed to 0123456789DEABCF(the letters have been used because ↊ and ↋ are not covered by many fonts and because the other 4 tonal numbers are not in unicode) and then everyone can use it, even the dozenal nuts)
hell you could even do the IPA and extIPA
oh and letting hidden power be fairy would be nice as well.
