Hi,
please, let's keep the discussion on the ML.

QString operates on UTF-16, not UCS-2.

Neither of these relates to some specific Unicode version.
QChar is a 16-bit Unicode character part. QString is UCS-2-encoded. Read
about UTF-16 for more info.
Also !qdoc: QChar::highSurrogate(), QChar::lowSurrogate()

Maybe in Qt 7.
(No, this is not a typo)

Hi Konstantin,
that is exactly what I did.
From the Qt5 documentation:

No, a QChar is exactly an UTF-16 code unit.

Isn't it supposed that a QChar contains a Unicode character (which is 32-bit in
size)?

[2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD]

in XML 1.0 is quite the same as
[2] Char ::= [#x1-#xD7FF] | [#xE000-#xFFFD] | [#x1-#x10] /* any
Unicode character,
All XML validation in Qt is based on XML 1.0 (and not the newer 1.1 standard).
I found at least 3 places where validity is checked:
1. in qxmlstream.cpp:
Method resolveCharRef:
//checks for validity
ok &= (s == 0x9 || s == 0xa || s == 0xd || (s >= 0x20 && s <= 0xd7ff)
16 matches
