 * Implementation of the system function interface for the R/3 Unicode
 * kernel.  The functions declared here are to replace those system
 * functions which handle variables of type char. The implementation
 * of the external functions is in nlsui?.c, ? = 1, 2, 3, ... and in
 * the project i18n/sapu16.  The Unicode specific behavior of the
 * functions is documented in flat/nlsuidoc.htm and flat/sapu16doc.htm .

 *                     also when compiling on NT in unicode debug mode.
 *                     Reasons:
 *                     - Avoid creating different code in debug and release mode
 *                     - NT iswxxx functions can be called directly allthough
 *                       they expect wint_t as paramter instead of int, because
 *                       the conversion is done implicitly

 * 22.03.2000 meb      Add an empty implementation of nlsui_initial_setlocale
 *                     for NT because currently there is not UTF8 locale,
 *                     but offering the function now will probably make it

 * sapuc.h  - compilation switches
 *
 *  There are some compilations switches which have to be derived
 *  from the global switch SAPwithUNICODE and platform switches.
 *  For every platform that supports Unicode,  the following switches must
 *  be set:
 *
 *   SAP_UC_is_1B   or  SAP_UC_is_wchar  or  SAP_UC_is_UTF16_without_wchar
 *
 *                   WCHAR_is_UCS2 or WCHAR_is_UTF16 or WCHAR_is_UCS4
 *
 *  The typedef for SAP_UC (SAP_UC_is_...) has been made in saptypeb.h already.
 *  SAPwithICU is set for all platforms where we use the ICU shared libraries.
 *  The switch
 *    WCHAR_is_2B  or  WCHAR_is_4B
 *  is needed for the definition of SAP_UTF16 and thus also in the non-Unicode
 *  case.

 *
 * The case           #if defined(SAP_UC_is_1B)

 *
 * The Unicode implementation is currently based on the type
 * --  wchar_t     if (sizeof(wchar_t)==2)
 * --  wchar_t     if (sizeof(wchar_t)==4)  and  SAP_UC_is_wchar

 *                         is for temporary testing only.
 *
 *
 * SAP_UC_is_wchar or SAP_UC_is_UTF16_without_wchar
 * are defined in saptypeb.h .
 *
 * In sapuc.h we distinguish as follows:
 *

 *         ... /o    No Unicode   o/
 * #else
 *             /o    Unicode U-functions that are independent of

 *   #if defined(SAP_UC_is_wchar)
 *             /o    Unicode U-functions or macros that use wchar_t       o/

 *   #endif
 * #endif
 *
 *
 * Source code that depends on SAPwithUNICODE but not on the implementation
 * of Unicode should look like:
 *
 * #if defined(SAPwithUNICODE)
 *         ...
 * #else
 *         ...

 * sapuc.h  -  NLS specific functions (multibyte functions)
 *
 *  MB_CUR_MAX was used to distinguish between multibyte-enabled code
 *  and single byte code. In the Unicode case, we have a similar
 *  distinction between UTF-16 enabled code and UCS2 code. There are
 *  three macros that allow to distinguish three possible cases:
 *  1. MB_CUR_MAX_U
 *     Code that is valid for both multibyte and UTF-16.
 *  2. MB_CUR_MAX_NUC
 *     Code that is valid for multibyte but would be unnecessarily
 *     complicated for UTF-16.
 *  3. MB_CUR_MAX_UC
 *     Code that is valid for UTF-16 but would not be correct for
 *     multibyte.
 *  By default, MB_CUR_MAX should be replaced by MB_CUR_MAX_NUC.
 *  As long as MB_CUR_MAX is not yet replaced in all cases, we must
 *  #define it to be (1) in the Unicode case n order to avoid running
 *  into the multibyte code.
 *
 *  mblenU() can be used in all three cases to identify sequences
 *  of SAP_CHARs that form one character (either a multibyte character
 *  or a surrogate pair).
 *
 *  Conversions between multibyte and wide characters are reduced
 *  to a memcpy in the Unicode case.
