Thank you very much for your helpful reply Gordon!
I recently upgraded to 2v12 and can confirm the new 'stroke' event works on my Bangle.js 2. I think I understand now how to implement letter recognition thanks to your example code but I guess the accuracy will depend on how forgiving your stroke matching algorithm is (hopefully I'll be able to learn more about that from the source code...).
Thank you as always for all your help and hard work!
