    GetCharacters Method (IScreen)
    In This Topic
    Gets ScreenCharacter objects from the specified location, each representing one character at a screen location. The length argument specifies the number of screen bytes to get. In SBCS, the number of screen bytes is the same as that of ScreenCharacter objects. In DBCS, the two numbers can be different. If the last byte is only one half byte of a DBCS character, the last byte is not returned.
