id3lib

I'm trying to create an ID3_Tag for a file whose path name is like:

"C:\Bart=F3k\01-The System-TEST.mp3"

In my application, I have the path name as a Windows-type wchar_t pointer. =
 I can convert it to UTF-8 easily, or to any other character encoding with =
some work.

If I try

myTag.Link(fileLoc, ID3TT_ID3V2);

and fileLoc is UTF-8, then Link() fails.  (As a UTF-8 string, the =F3 is ex=
panded to 0xC3 0xB3).  And there doesn't appear to be a way to Link() with =
a whcar_t version of fileLoc.

It looks like Id3lib tries to open the file in utils.cpp in ID3_Err dami::o=
penReadableFile(String name, ifstream& file) and it uses file.open(name.c_s=
tr() where file is an std::ifstream

I'm digging through and experimenting with the source code to try to figure=
 out a way to fix this ... by any chance does anybody know a relatively eas=
y solution to this?  Should I be converting the file path name to ISO-8859-=
1 (if I am remembering the "typical" windows code page correctly)?

There doesn't seem to be an equivalent call to Link() for wchar_t, or UTF-8=
.  I kind of hate converting the string -from- unicode to a code page ... I=
 guess that would probably not lead to data loss, the c++ std functions are=
 probably going to recognize 8859-1, because that is what windows is using =
at least in the file system.

When I get the file path name from windows though, I have their idea of "UN=
ICODE" enabled, so Windows is giving me the path in whcar_t.

Anyway ... I am going to keep experimenting with this and digging through t=
he code, but I am about to break for lunch so I am hoping somebody might be=
 reading the list and have an easy solution to this, because it is probably=
 going to be a couple of hours at least of trial and error the way I'm doin=
g it.

Thanks for any help.

This is probably a stupid question ...

I just set up id3lib and set up a test project, everything's working great.

But I just managed to confuse myself ... there were comments in the test pr=
ojects I was basing my test on that said:

// use an std::auto_ptr here to handle object cleanup automatically

Do I need to do something special to be sure that the memory allocated by a=
n id3lib object gets freed when I'm done with it?  That is, if I create an =
object like this

//scope
{
  ID3_Tag myTag("myfile.mp3");
}
//out of scoped

Is everything going to be freed when the object goes out of scope?

Usually an std::auto_ptr as far as I know would just be used if an objects =
creation/scope/ownership is ambiguous, but would just call delete on an obj=
ect allocated with new automatically when it goes out of scope ... so, it s=
eems like in this case it would not be doing anything.  (Either way, the en=
d result would be that the destructor for ID3_Tag gets called, it seems lik=
e it would work the same either way).

I am guessing probably that comment was just a note from the person writing=
 the example to himself/herself and I am making something out of nothing.

Anyway sorry if I am making something out of nothing but I thought I should=
 double-check before I wound up with a memory leak.
