'3D' HTML emailer code


I’ve just checked the raw source of an email I received from Apple and came across ‘3D’ throughout. Seems to be before every " after each =.

<td width=3D"40" bgcolor=3D"#FFFFFF">&nbsp;</td>
<td width=3D"45" bgcolor=3D"#FFFFFF">
<p style=3D"padding:0 5px 0px 0px;">
<img src=3D"http://developer.apple.com/click/images/icon_safarimobile.jpg" =
alt=3D"Web Development Guidelines" width=3D"45" height=3D"45" border=3D"0">

Any ideas why it’s there or what it’s for?

It seems to be an encoding issue. This thread discusses the same problem and offers a solution.

(“=3D” is the quoted-printable representation of character U+003D, which is the ‘=’ character.)

Thanks for that, I thought it was something fancy as it came from Apple :wink:
