Yes, you need to use Vstring, Varchar or Vtext fields.

Yes, you need convert into MacRoman.

Thee is no other ways to work with strings now.
In fact very good way that have work for all us for years :-)

The main difference how they are stored on disk.

    Vstring[100]
    VarChar[100]   


All looks the same for you outside.
But if you will store 1000 records with value "test" in first case you will
get eaten 1000 * 100 = 100KB  on disk. In the second case you will eat just
1000 * (4 + 4) = 8KB or so.

But Vstring is more effective for short strings e.g. < 20-40 bytes.
