83
* <p>These definitions allow to specify the encoding of text
84

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>
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>
93
* <p>The list of "invariant characters" is:<br>
95
* A-Z a-z 0-9 SPACE " % & ' ( ) * + , - . / : ; < = > ? _
98
* (52 letters + 10 numbers + 20 punc/sym/space = 82 total)</p>
100
* <p>This matches the IBM Syntactic Character Set (CS 640).</p>
102
* <p>In other words, all the graphic characters in 7-bit ASCII should
103

441
* a) Check for imports of global new/delete (see uobject.cpp for details)
442
