Exactly. And=20
QString ( QChar ch )
works too. But remember that a char is a number,"a" is a string instead. So=
=20
you have to use use
$mystring =3D new QString(65);

Normally it is possible to provide all constructors, but the others are sti=
ll=20
broken in the current version. Next time I will fire up an improved kalyptu=
s=20
script again to solve it.

it should print "h=C3=A1llo" to console.

The string is stored in the QString object. The zend engine passes it from=
=20
your code to the object. In your tests you have proven that it works.

The fromUtf8 function does not work for me, I got segfaults.

What is with this piece of code:
$text =3D new QString($my_database_fetched_variable);
$myLineEdit->setText($text);

Note, what we are doing is experimental and the php guys are working on the=
=20
same problems with other tools. I read some of Andrei's implementations in=
=20
php6 and they implemented a function which copies unicode strings to normal=
=20
php strings. For php_qt this should be done by Qt's QString::toAscii(), I=20
passed the resulting bytearray to a string directly.
