size of QChar

hi
The QChar doc says

Quote:

---

The QChar class provides a 16-bit Unicode character.

---

But it seems a single character is stored as one byte.

Code:

---

QChar ch('a');
QByteArray arr(QString(ch).toAscii());
qDebug()<<arr.size();//The OutPut is 1.

---

I had expected the size to be 2 bytes.

From QString::toAscii:

Quote:

---

Returns an 8-bit ASCII representation of the string as a QByteArray.

---

i have already used it in example of first post.

I mentioned it to explain why size() returns 1.

QString::toAscii() returns the 8-bit ascii representation of the character.

So

Code:

---

QString(ch).toAscii();

---

takes your 2-byte Unicode character and returns the 1-byte ascii version of it, hence arr.size() gives 1.

where is the other byte.
