83 * <p>These definitions allow to specify the encoding of text
84 * in the char data type as defined by the platform and the compiler.
85 * It is enough to determine the code point values of "invariant characters",
86 * which are the ones shared by all encodings that are in use
87 * on a given platform.</p>
88 *
89 * <p>Those "invariant characters" should be all the uppercase and lowercase
90 * latin letters, the digits, the space, and "basic punctuation".
91 * Also, '\\n', '\\r', '\\t' should be available.</p>
92 *
93 * <p>The list of "invariant characters" is:<br>
94 * \code
95 *    A-Z  a-z  0-9  SPACE  "  %  &amp;  '  (  )  *  +  ,  -  .  /  :  ;  <  =  >  ?  _
96 * \endcode
97 * <br>
98 * (52 letters + 10 numbers + 20 punc/sym/space = 82 total)</p>
99 *
100 * <p>This matches the IBM Syntactic Character Set (CS 640).</p>
101 *
102 * <p>In other words, all the graphic characters in 7-bit ASCII should
103 * be safely accessible except the following:</p>
