Hi All,
I've started some work towards supporting Unicode in CMake so I could get
better support for building/testing our internationalized applications.
https://github.com/clintonstimpson/CMake/commit/f08ca2ff65f434b2bc404000765a836880f78f0e
It keeps char* / std::string throughout the code where utf-8 is assumed on
Windows and the current encoding on other platforms (usually utf-8).
Conversions to wchar_t are done on demand when calling Windows apis. In other
words, its mainly just a change to move towards unicode aware apis on Windows.
It calls the wide version of Windows apis explicitly, so it does not matter
whether one is compiling with -DUNICODE/-D_UNICODE or not. I assumed Win9x
support is no longer needed, so there was no attempt to enable calling the old
ANSI version of the apis.
I haven't gotten as far as I hoped because of unicode limitations in Visual
Studio. For example, custom commands in visual studio executed with cmd.exe has
problems with encoding. When I reported this to Microsoft, they said it works
better on Windows 8, but I don't have that right now. I was able to make my own
utf-8 .bat files and call cmd.exe (with appropriate settings) myself and it
worked just fine. Somehow, its different when Visual Studio does the same for
custom commands.
Any feedback or patches would be appreciated. For instance, std::ifstream/std::
ofstream/fopen need to be done special, and maybe some of you would prefer to
have a wrapper for that.
There are plenty of changes in KWSys so the patch probably needs to be split
up.
Although probably not an entire solution, it gets us part of the way there. I
think this scope of changes can be merged in and further work done later which
can include others. Overall, these changes don't really change the programs
behavior except that some things which have already been working on other
platforms start to work on Windows.
Clint
