Problem using TagLib::FileRef under Windows with exotic filename

[Tanguy Krotoff]

Did you try this macro ?

/** Converts a Qt4 QString to a TagLib::String. */
#define Qt4QStringToTString(s) TagLib::String(s.toUtf8().data(),
TagLib::String::UTF8)
there is also the TStringToQString macro

Use of these macros:
TagLib::String str(Qt4QStringToTString(fileName));
TagLib::FileRef fileRef(str.toCString());

TagLib::Tag * tag = fileRef.tag();
if (tag) {
	if (!tag->isEmpty()) {
		_title = TStringToQString(tag->title()).trimmed();
		...


I think it is the "official" way to deal with UTF8, TagLib and Qt4
(I found theses macros somewhere inside TagLib source code)
