Yes (well, not full regexes, but a partial implementation). But....

....no, because the "space" is not a character that will ever be seen  
by the font mapping. By the time strings of text are run through the  
font mapping, the space (or newline) has become interword "glue" in  
TeX's current horizontal list; it's not a "text character" at all.
