Very few emulators get them right; I've yet to see one that's 100%
accurate.  The characters from an SAA5050 are much higher resolution 
than 5x7 because of the interlacing, actually 10x14 IIRC.  That's why 
they look less "jaggy" on a real Beeb or most other systems that use 
SAA5050 chips.  If you have access to a real Beeb, try turning the 
interlace off in mode 7, and you'll find the characters look very odd, 
because you're not seeing all the pixels.
