Hi everyone. I would like to know if I can insert any character in a math formula built with equation editor. I try to explain the problem. When writing a Mathematics text, I use frequently the "double struck capital" characters (to denote for example the set of natural or integer numbers). I found these characters in the set "Cambria Math": for example, the special "N" which denotes the set of natural numbers corresponds to Unicode 2115, the "Q" for rational numbers has the code 211A, and so on. So, there is no problem inserting these characters along the normal text. But sometimes I need inserting them inside an equation, and unfortunately it doesn't work. I tried to change style (choosing "Other"), but I obtain a normal "N" from the Cambria Math font, not the special "N". I also tried to copy the character form the text inside the equation, but I only obtain a "?", and the error message "Equation too big, cannot convert it". How can I solve the problem?

A final remark: I previously used the font "Mathematica 7 Mono", which was automatically installed with "Mathematica" but could also be installed independently in the computer. I had no similar troubles with these font, since I was able to select "Other style" in Equation Editor, and it worked properly. But now I cannot find this font on the web, and for this reason I used Cambria Math.

Thank you for your attention
