I'd like to change the list of characters that show up when I click the 'Special Characters'.   I want to delete the alphabet and some other characters that you display (because those aren't special characters), and I want to insert only the special characters that I need.  How do I do this?

 

Also, when I insert a unicode  character, the following is inserted:    <font class="UNICODE">λ</font>

Why is the <font> tag added ?

 

Thanks,

Jim
