One of our members posted in our forum about how Hotmail was replacing their HTML Copyright, Registration and Trademark symbols with an image, despite trying multiple types of character encoding.
After doing a little research, it seems that additional users are experiencing the same issue, based on this thread on Microsoft’s Hotmail forum.
We have confirmed that this new phenomenon occurs in all browsers and that it is exclusive to Hotmail. Here are some of the characters that get converted: ® (®), ™ (™), ©(©), ♠ (♠), ♣ (♣), ♦ (♦) ♥ (♥).
After some brainstorming and additional research, Miki has found a fix that’s pretty short and sweet.
