*   12/11/96    helena      Creation.
*   02/27/97    aliu        Added typedefs for UClassID, int8, int16, int32,
*                           uint8, uint16, and uint32.
*   04/01/97    aliu        Added XP_CPLUSPLUS and modified to work under C as
*                            well as C++.
*                           Modified to use memcpy() for uprv_arrayCopy() fns.

 *
 * <p>These definitions allow to specify the encoding of text
 * in the char data type as defined by the platform and the compiler.
 * It is enough to determine the code point values of "invariant characters",
 * which are the ones shared by all encodings that are in use
 * on a given platform.</p>
 *
 * <p>Those "invariant characters" should be all the uppercase and lowercase
 * latin letters, the digits, the space, and "basic punctuation".
 * Also, '\\n', '\\r', '\\t' should be available.</p>
 *
 * <p>The list of "invariant characters" is:<br>
 * \code
 *    A-Z  a-z  0-9  SPACE  "  %  &amp;  '  (  )  *  +  ,  -  .  /  :  ;  <  =  >  ?  _
 * \endcode
 * <br>
 * (52 letters + 10 numbers + 20 punc/sym/space = 82 total)</p>
 *
 * <p>This matches the IBM Syntactic Character Set (CS 640).</p>
 *
 * <p>In other words, all the graphic characters in 7-bit ASCII should
 * be safely accessible except the following:</p>
 *
 * \code
 *    '\' <backslash>
 *    '[' <left bracket>
 *    ']' <right bracket>
