[Cppunit-devel] Unicode

[Baptiste L. <bl...@cl...>]

Michael Arnoldus gracefuly sent me a unicode version of CppUnitW 1.2.

The change required to add unicode support in cppunit are:

* having alias to std::string or std::wstring depending on weither we are
compiling for unicode or not. This also apply to ostrstream, cerr, and cout.

Michael did it that as follow:

#ifdef _UNICODE
#define _tstring wstring
#else
#define _tstring string
#endif

This could probably be done using typedef and creating string in CppUnit
namespace too:

#ifdef _UNICODE
typedef std::wstring string
#else
typedef std::string string
#endif

* having a macro _T which make the specified string unicode when needed:
  std::_tstring( _T( "Unknown" ) )

* adding a function ustring( const char *) to estring.h to construct a
unicode string from a const char *string.
  This one is a problem for portability. Mapping from "char *" to unicode is
done using WIN32 API.
  So how is that done on unix. Is there a single API for all Unix to do the
mapping ? (I know that QT support unicode and is portable, but not how
difficult it is to achieve on Unix)

* adding new configuration to projects setting for VC++

(Michael let me know if I forgot something)

Note for Unix developper:
The _t thingy is a win32 idiom. We have a tchar.h header which provides all
string function with such a prefix, aliasing to either single byte character
string or unicode character string function depending on _UNICODE symbol.

Is there such an idiom for Unix ?

Here is the "Unicode TODO" list that I can see for now:
- make a new header file which contains all stuffs relating to unicode
(macros, typedef...)
- replace character dependent object used in cppunit with those defined in
the previous header
- add the ustring function.

I'm can do all those stuffs but we need to define the specific (header file
name, define/typedef, alias name, _T name...).
