My environment : OSX, C++, g++, libPDFNetC.dylib.6.5.3
While evaluating PDFNet SDK i tried to open a PDF document having a special character (german umlaut "ü") in its filename:
The string containing the filename is UTF-8 encoded ("ü" correctly represented as "\xb3\xbc").
Although the file exists the ctor fails with an exception:
Message: File does not exist.
Conditional expression: fs::exists(some_path) && !fs::is_directory(some_path)
Filename : MappedFile.cpp
Function : Init
Linenumber : 63
Using lldb and a breakpoint on syscall "stat" i found out that the string passed to "stat" has been UTF-8 encoded a second time (!): i.e. the UTF-8 sequence "\xb3\xbc" i passed to the ctor of PDFDoc became "\xc3\x83\xc2\xbc". it is no surprise that stat fails with this invalid filename.
I was experimenting a bit and found that if i encode the filename using CP1252 (using iconv()) then the document will be opened successfully.
As the locale is set to UTF-8 it should be possible to use UTF-8 encoded filenames!? shouldn't it?
thx for your help.
