Horizontal Cursor Move

In short,

• If the right arrow key is pushed and the current character is DBCS, you should move the cursor two display positions to the right.

• If the left arrow key is pushed and the next character on the left is DBCS, you should move the cursor two display positions to the left.

  For example,

  aD1D2b <-> aD1D2b <-> aD1D2b <-> aD1D2b
  -           -            -            -
