Hyperlinks in PDF documents not working

[grunt2651]

We are creating documents in html, which we then run through an html-pdf converter to have a pdf document that is emailed as an attachment. We have a document that we want recipients to be able to respond to by email, so are using the html mailto tag to create a hyperlink within the document that recipients can then select to create a reply email with address and subject line pre-populated.

This works quite okay when tested on a PC, the link within the PDF document responds as desired within Outlook and Adobe Reader.

However, we have discovered that if the email is read on an iPhone or Samsung phone the hyperlink within the pdf does not appear to work. Any attempt to select the hyperlink simply selects the text and allows the usual copy etc. options for selected text. This appears to be the case in either the email app on the phone or even when opening the attachment in Adobe Acrobat app.

Is there a way we can have this reply email hyperlink working regardless of what platform the email is received in?

In further testing of this problem, we have tried sending the document as an html file prior to conversion to PDF, and the hyperlink still responds in the same way on iPhone mail. Therefore it seems to be something to do with the way the mobile devices are handling embedded hyperlinks in file attachments.

Can you share a sample file?

Here is a sample PDF document that shows what I am trying to achieve with the embedded mailto hyperlink

It will work in Acrobat Reader on mobile devices when you remove the spaces from the subject.
