Email QRCode shows "+" instead of spaces in subject and body

[duongnx25]

Hi, I see this has been reported before but I still have it.
When generating a QR code using the email function, if subject and body have space and scan the QR code using Iphone, the Mail app of Iphone will convert all space to "+".
This doesn't occur on Android

Here's an example SVG file:

If instead of leaving the spaces you correctly URL-encode the URL before passing it to the QR code, so that the spaces are percent-encoded (e.g. mailto:[email protected]?subject=Testing%20a%20multi-word%20subject)

Does that work?
