Short answer is no.
Take a look at the YoYo Store, there are quite a few extensions that will parse your string to give a similar appearance, but then you have to create multiple fonts. i.e. font0_normal, font0_underline, font0_bold, font0_italic, font0_bold_underline, font0_bold_underling_italic (so it takes some work). That's about the best you can do at this juncture.
