I need to create a font hwereby i will replace all the capital letters
with subscript. There will be 10 munbers , 3 symbols borrowed from
other font and one character with the letters th joined. I need this 
font when i am transliterating other languages. I  want to  take a
font and customize it and rename it so that i can swap in and out of
my font into times roman when i am either typing normally or
transliterating. I would need it to be in italic only , no capital
letters.
I may have to borrow characters from say  bookman font.  Is bookman
the property of some company  or is it free to use and change. If not
is there a generic font i can use. Is that something easy to do ?   I
would appreciate any help.  Many thanks   solecat
