Update db.txt to 1220 characters
Update app so searches can be done on arbitrary length strings now. For
each character, a result will be printed indicating whether the
character was found in the database.

One caveat is that I'm not sure what behavior this has if there is a
newline in the string. And if the character is not a chinese character
it should be ignored. Will make a bug for this.
