Changing the font dynamically in stylesheet depending upon string /local

Hello List,
          Is is possible to change the font style
dynamically depending upon the type of string to be
displayed or locale. E.g. if it is Japanese I need to
set it MS Mincho, if it is US then MS Sans Serif. 
I swing I can know which type of font style supported
by the string and I want to replicate the same
behaviour in stylesheet.

regards,
Ranjan
