Hi,
I encountered a strange problem with the directory selection droplist of the FileSel dialog: The first entry is the home directory and is filled with dir.Add(GetHomeDirectory());. In the directory name a character 'á' gets replaced by another character (German double S) when the application executable is started stand-alone, but when started with Ctrl+F5 from TheIDE, there is no problem.
To figure out what's going on, I changed the GetHomeDirectory functionality in App.cpp by changing GetEnv() as follows:
String GetEnv(const char *id)
{
// return FromOEMCharset(getenv(id));
return FromSystemCharset(getenv(id));
}
What happened was, the character 'á' disappeared altogether when running the application from TheIDE, but was now correctly presented when the application was started as standalone.
Any idea what's going on here?
// Tom
[UPDATE: This is under Windows Vista x64 and the problem when running the application standalone was detected with 32 bit Windows XP, so they seem to have the same behavior.]

Nice one.
I believe I know what is going on.
The issue is that TheIDE changes the environment to add one special variable. Maybe this can affect the issue.
Anyway, staring into the code, I do not see anything indicating that codepage is changed on the way - in fact no conversions seem to be performed at all.
Relevant code is:
Core\App.cpp
void AppInitEnvironment__()
ide\Builders\Build.cpp
One<Host> MakeBuild::CreateHost(bool sync_files)
Perhaps adding a couple of well placed LOGs would reveal the problem.

Hi Mirek,
Well, I kind of knew you would know what is going on... Anyway, I took a look at the source locations you pointed out but I did not get any smarter on the way. I guess this needs deeper understanding on the subject than what I have.
I gather that this problem has wider effects than just the file dialog. The whole GetEnv and everything using it (including GetHomeDirectory) are broken until this gets solved.
