/**
* @class vtkCharArray
* @brief dynamic, self-adjusting array of char
*
* vtkCharArray is an array of values of type char. It provides
* methods for insertion and retrieval of values and will
* automatically resize itself to hold new data.
*
* @warning
* This class should be avoided in favor of either
* vtkSignedCharArray or vtkUnsignedCharArray. On some systems
* the underlying data will be stored as unsigned chars and others
* it will be stored as signed chars. Additionally, saving this
* array out and then reading it back in it could be transformed to
* a vtkSignedCharArray or vtkUnsignedCharArray and if that happens
* the result of a vtkCharArray::SafeDownCast() of that pointer will be
* a null pointer.
