I got a problem that seems unsolvable. The problem is in generating the QR code that will call one specific number. Number format is *103*14 digit activation number# and reading it with an android QR code application causes absence of hash sign (#) in call form. I googled it and the conclusion is that android API for some reason prevents reading hash sign from the QR code. Workaround for android OS is using URI encoding for hash which is %23, in that case it works like a charm. But reading the same QR code with the iOS QRReader application doesn’t convert %23 to hash, instead it just shows 23. Is there a solution that covers all of these problems? Thank you in advance!

You have to double-encode the hash, so the percent sign is also encoded.
So, the # becomes %2523
Scan this QR code and your phone dialer should show *#67#
