[Development] [Question] Implementation of XML character validation

[Kurt Pattyn]

Hi Konstantin,

that is exactly what I did.
From the Qt5 documentation:
> The QChar class provides a 16-bit Unicode character.
> In Qt, Unicode characters are 16-bit entities without any markup or structure. This class represents such an entity. It is lightweight, so it can be used everywhere. Most compilers treat it like a unsigned short.


There is no mention of UTF-16. Furthermore, I would expect to method unicode(), to return the UCS-4 representation:
> ushort QChar::unicode() const
> Returns the numeric Unicode value of the QChar.

But, it doesn't return the unicode v6.2 value, as that can be 32-bit; I know. It gives me the impression that QChar is based on an old Unicode standard.

Furthermore (again from the documentation):

> Qt 5.0 uses and fully supports version 6.2 of the Unicode standard.


At least, I think this is confusing.

So, either the documentation of QChar should at least indicate that it is encoded in UTF-16, which I doubt (because then QChar should have place for 2 16-bit values), or QChar should be adapted to conform to the statement that Qt5.0 is Unicode 6.2 compliant, or it should be indicated that QChar conforms to an older standard.

So, I was just wondering how QChar fits within the Unicode 6.2 standard? Reading the docs doesn't clarify much.
