You can use only:

\b = Backspace 
\f = Form feed 
\n = New line 
\r = Carriage return 
\t = tab
\000 = octal character 
\x00 = hexadecimal character 
\u0000 = hexadecimal unicode character

So, you can insert different ASCII characters, but not format them (like italic or bold).

EDIT I also have to mention, that in fact alert acts like toString conversion, so including tags and/or styles is not possible.
