QString tmpStr=QString::fromWCharArray(L"\xD83E\xDDB7");
myStr.remove(tmpStr);

You already know the answer - specify it as a proper UTF-16 string.

Unicode codepoints above U+FFFF are represented in UTF-16 using a surrogate pair, which is two 16bit codeunits acting together to represent the full Unicode codepoint value. For U+1F50E, the surrogate pair is U+D83D U+DD0E.

In Qt, a UTF-16 codeunit is represented as a QChar, so you need two QChar values, eg:

edit.setText(QString::fromWCharArray(L"\xD83D\xDD0E"));

or:

edit.setText(QString::fromStdWString(L"\xD83D\xDD0E"));

Assuming a platform where sizeof(wchar_t) is 2 and not 4.

In your example, you tried using QString::fromUtf8(), but you gave it an invalid UTF-8 string. For U+1F50E, it should have looked like this instead:

edit.setText(QString::fromUtf8("\xF0\x9F\x94\x8E"));

You can also use QString::fromUcs4() instead:

uint cp = 0x1F50E; edit.setText(QString::fromUcs4(&cp, 1));
