Hi C++ folks,
I have trouble to open files whose path contains non-ascii characters
with std::ifstream.
For instance let's say i just have a file which has Japanese
characters either in the file path or the file name :
=E7=96=91=E5=95=8F.dat=
. The
file itself does not contains unicode characters or whatever, it is a
binary file, but the file name, or path, contains non-ascii
characters, here it is Japanese but it could be anything else, i know
nothing about my customers languages.
On Linux, simply doing this :
std::ifstream ifs('=E7=96=91=E5=95=8F.dat"); just works, i can open the
file=
.. Of
course in my app file path are not hard coded in the source code, the
user choose his file using a file dialog. The file dialog returns me a
QString (Trolltech Qt framework). If the returned QString is named
filepath, then std::ifstream ifs(filepath.toUtf8()) works fine too.
The problem is my application is cross-platform, and on Windows XP the
2 above pieces of code does not work at all ! The ifstream fails to
open the file ... I suspect this is a locale issue, i just know my
Linux distribution uses UTF-8 by default, this must be why it works,
whereas on Windows, it seems strange, ifstream.getloc().name() returns
just "C" , and if i create a default locale with std::locale
my_locale("") , then my_locale.name() returns French_France.1252 ...
I'm stuck with all this locale/encoding problems, it is not clear in
my mind, to solve a problem firstly you need to understand the
problem, and i think i don't :-) I wonder if i have to change the
locale on Windows to a UTF-8 one (i didn't succeed), if i have to use
some conversion functions, or wifstream, or wstring, even after
searching on Google i didn't made any progress, internationalization
stuff does not seem to be trivial with C++ .
Any help, hint, or suggestion would be appreciated !
Regards,
Micha=C3=ABl
