mailto: hyperlink - Making the body Bold

Hello all.

I have an anchor on my page that has the mailto: feature with subject, and body as well.

There are some parts of the body that I would like to bold. I've tried tons of ways, and whatever I use, it appears into the mail body as text. Html does not work.

When I need a line break, I use '%0A'. And that works well.

Is there a tag to bold specific text?

Thank you.

The only way to bold the body is to use <b> </b> tags and the email must be in HTML format.
