Quikscript is a phonetic alphabet for English, closely related to the Shavian alphabet which had, in fact, the same creator. Ronald Kingsley Read invented Quikscript in 1966, four years after Shavian, implementing a lot of the feedback he’d received. Quikscript is sometimes known as “Second Shavian”.
Quikscript is designed to work better for cursive handwriting than the original Shavian. There are two varieties of Quikscript – Junior Quikscript, which is printed letters, and Senior Quikscript, which is full cursive. Junior Quikscript looks very similar to Shavian, with many shared letters, even though there are also many differences. Some of these include the reallocation of 𐑥 and 𐑯 to the palm and thought vowels, respectively (in Shavian they represent /m/ and /n/), the reallocation of the “th” letters to letters that look like mirrored/rotated forms of 𐑖/𐑠, and the existence of like six letters that all look like mirrored/rotated versions of 𐑞/𐑔, including m/n (in Shavian those letters represent /ð/ and /θ/).
There is no Unicode support for Quikscript. Honestly, I don’t see any reason why I’d want to learn or use it over Shavian. Maybe if we were still in the days of needing to handwrite everything, but even then my normal handwriting is only semi-joined, so the added complexity Senior Quikscript introduces just for the sake of fluid cursive seems really undesirable to me.
