Hello,
I know you are not supposed to write commas in shorthand, but when writing a text in shorthand that you want to keep with you for a long time (like a diary or personal notes) or to share with others, commas can really become indispensable.
So I was wondering if an inverted comma (by that I mean, written downwards and from left to right) could do the trick and avoid any confusion with an isolated S (which is written from right to left like a regular comma). I know that another solution is to circle your comma but that sounds a bit cumbersome.
Thanks!
