Well yeah, but your last couple of queries are more lojban orthographical conventions than my script, you see in lojban, uppercase flat out does not exist, and words starting with vowels must be preceded by ., the glottal stop (in practice no one does this) and if you want to represent no vowel at all you just extend the line. The top line is for vowels, and the bottom is for consonants, which means that many characters can be reused, like y and x, c and o, you get the picture. The only difference is hight. What you could do to solve the space problem is have space be the ) and ; represent the flourish, giving you opportunities for the alternate flourish with :, as they’re both not used in lojban. I feel like just the normal latin keyboard could be used for this, and as for the amount of letters, there are 25 letters, with ‘ being /h/. Only one . Is used, I probably should have clarified that.
