issue with " caracter on iOS

[mglavind]

when trying to create a meme in iOS using the standard keyboard, one would get this caracter: “, in stead of " caracter, causing the script to interprete /meme brian “some text“ as a text string ' “some text“ ', and thereby corresponding to /meme brian "“some" "text“" not creating the correct meme.
Suggestion : auto replace “ with " in all strings
