| * 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. |
| * 04/14/97 aliu Added TPlatformUtilities. |
| * 05/07/97 aliu Added import/export specifiers (replacing the old |
| * broken EXT_CLASS). Added version number for our |
| * code. Cleaned up header. |
| * 6/20/97 helena Java class name change. |
| * 08/11/98 stephen UErrorCode changed from typedef to enum |
| * 08/12/98 erm Changed T_ANALYTIC_PACKAGE_VERSION to 3 |
| * 08/14/98 stephen Added uprv_arrayCopy() for int8_t, int16_t, int32_t |
| * 12/09/98 jfitz Added BUFFER_OVERFLOW_ERROR (bug 1100066) |
| * 04/20/99 stephen Cleaned up & reworked for autoconf. |
| * Renamed to utypes.h. |
| * 05/05/99 stephen Changed to use <inttypes.h> |

| * <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> |
| * A-Z a-z 0-9 SPACE " % & ' ( ) * + , - . / : ; < = > ? _<br> |
| * (52 letters + 10 numbers + 20 punc/sym = 82 total)</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> |
| * '{' <left brace> |
| * '}' <right brace> |
