mailto link with HTML body

Question

I have a couple of mailto links in an HTML document.

<a href="mailto:etc...">

Can I insert an HTML formatted body in the mailto: part of the href?

<a href="mailto:[email protected]?subject=Me&body=<b>ME</b>">Mail me</a>

Note that (2016) in iOS, it is perfectly fine to add <i> and <b> tags for simple italic, bold formatting.

The special <hfname> "body" is used to indicate that the associated <hfvalue> is the body of the message. The "body" field value is used to contain the content for the first text/plain body part of the message. The "body" pseudo-header field is primarily used for the generation of short text messages for automatic processing (such as "subscribe" messages for mailing lists), not for general MIME bodies
