Summary0027838: Foundation Classes - support wchar_t* input within TCollection_AsciiString and TCollection_ExtendedString
DescriptionThe most used string classes in OCCT are TCollection_AsciiString and TCollection_ExtendedString.

TCollection_ExtendedString is intended to store UTF-16 string, while TCollection_AsciiString is for UTF-8.

Most systems just use UTF-8 strings in platform APIs - and thus "const char*" and TCollection_AsciiString can be transparently used there.
However, Windows supports only one way for passing Unicode strings - through "wide-char" APIs taking "wchar_t*".

The problem is that TCollection_ExtendedString defined UTF-16 characters in platform-independent manner and does not provide any means to handle "wchar_t*" strings (despite the fact that on Windows these types have the same size).
This requires very annoying conversion routines to pass / take Unicode string from Windows APIs - usually using static casts at every place.

It is proposed to extend TCollection_AsciiString/TCollection_ExtendedString classes to handle "wchar_t*" strings on Windows platform to make syntax more transparent to end-user.
Steps To ReproduceN/A
TagsNo tags attached.

    0027838: Foundation Classes - support wchar_t* input within TCollection_AsciiString and TCollection_ExtendedString
    
    TCollection_ExtendedString/TCollection_AsciiString description
    has been updated to reflect usage of this classes for Unicode strings.
    
    TCollection_ExtendedString now defines constructor taking wchar_t* (all platforms)
    and method ::ToWideString() returning wchar_t* (Windows only).
    TCollection_AsciiString now defines constructor taking wchar_t*.
    
    TCollection_ExtendedString/TCollection_AsciiString now defines
    auxiliary methods ::StartsWith() and ::EndsWith().
    
    TCollection_ExtendedString internals has been updated to eliminate
    duplicated code for converting between UTF-16 and UTF-8.
    The internal method Allocate() in TCollection_ExtendedString.cxx
    now automatically NULL-terminate allocated buffer.
    
    Code has been cleaned up from redundant explicit conversions to wchar_t*.
    Global method OSD_OpenStream()/OSD_OpenFileBuf() have been replaced
    by C++ template to eliminate copy-paste for different STL collections.
    
    OSD_SharedLibrary now uses wide-char system API call LoadLibraryExW()
    on Windows for consistency.

Some remarks:

1. In OSD_File.cxx, 2791:

- if ( !OpenPrinter ( Standard_PCharacter(pName), &hPrinter, NULL ) ) {
+ if ( !OpenPrinterW ((wchar_t* )pName, &hPrinter, NULL ) ) {

this conversion is suspicious since pName is still PCharacter, i.e. char *

2. In TCollection_ExtendedString, methods Re/Allocate():
- perhaps it is better to use size in characters, not in bytes
- it is somehow innatural to delegate the task of setting terminating null symbol to allocation function... the code would be less confusing if null was added explicitly whenever string is filled

3. In TCollection_ExtendedString, run-time "switch (sizeof(Standard_WideChar))" should be replaced by compile-time equivalent, e.g. using template specializations. For an example of the technique, see OCCT_InverseSizeSpecialized in FSD_BinaryFile.cxx

4. In TCollection_ExtendedString.hxx, I suggest removing "has been decided to " and replacing "might not" by "can miss". Idem replace "NULL-terminated symbol" by "terminating NULL symbol"

-  if (  !OpenPrinter ( Standard_PCharacter(pName), &hPrinter, NULL )  ) {
+  if (  !OpenPrinterW ((wchar_t* )pName, &hPrinter, NULL )  ) {

Should be const_cast<wchar_t*>

 Please check updated patch in branch CR27838_2 which should workaround awkward compatibility issues.

It seems that compilation issues in Qt samples caused by using deprecated msvc compilation flag "-Zc:wchar_t-" which makes wchar_t as not built-in type.
This issue has been fixed in Qt5, so I suppose old Qt4 is used for building samples:
