[Tugindia] zero nbh and Power set symbol

[Bhaskaracharya Pratishthana]

Hi,
Is there any symbol to denote Power set? Which is used in measure theory 
do denote POWER SET=P but different P. Also L= running capital L. Also 
to denote zero neighbour hood.
I tried some site, mentiined in the list earlier, but could not connect 
to it.

Thanks!
