Hi all!

I hope there are some Russian developers on this list.
(I guess the same problems would occur with Hebrew
texts.)

The problem is: Russian users can input Cyrillic
lyrics in my musical score editor NoteEdit:

http://rnvs.informatik.tu-chemnitz.de/~jan/noteedit/noteedit.html

They also see the Cyrillic text on Q(x)Widget. But if I write
the lyrics to some file and try to restore them the text
is destroyed.

Unfortunately I have no Cyrillic keyboard and thus, I can't
input Cyrillic lyrics. But I made test with German Umlauts
(HTML: &auml; &ouml; &uuml; ...; &szlig;).

I wrote a simple test class "UTFText" which works so far.
Perhaps some Russian devopers (and/or others (???)) could please
have a look at my intentions. Or perhaps there is a instruction
page to avoid problems with non-ascii-glyphs:

The class is:

 class UTFText : public QDialog {
        Q_OBJECT
        public:
                UTFText(QWidget *parent = 0);
        protected:
                virtual void resizeEvent ( QResizeEvent * evt);
        private:
                QPushButton *writeText_;
                QPushButton *readText_;
                QTextEdit *ifeld_;
        private slots:
                void readInternationalText();
                void writeInternationalText();
 };

Important are only the implementations of the 2 slots which
shall write/read the text in "ifeld_" as UFT8
(or should I use Unicode ???) to some file:

#define TEXTFILE "/tmp/xxx.txt"

 void UTFText::writeInternationalText() {
        ofstream out;
        out.open(TEXTFILE);
        if (!out) { /* error */ }
        out << ifeld_->text().utf8() << endl;
        out.close();
 }

 void UTFText::readInternationalText() {
        char buffer[1000];
        QString s;
        ifstream in;
        in.open (TEXTFILE);

        if (!in) { /* error */ }
        in.getline(buffer, 1000);
        s = QString::fromUtf8(buffer);
        ifeld_->setText(s);
 }
