pyside6 QLineEdit, QTextEdit Korean combination error

Freemize

pyside6 There is a problem with Korean input when using QLineEdit and QTextEdit.

There is a problem that the Korean combination with ‘ㄲㅗㄹ’ is not possible when entering ‘꼴’ with the keyboard.

Please help from Qt developers.

Here is the code I tested:

import sys
 
from PySide6.QtCore import Qt
from PySide6.QtWidgets import (QApplication, QGridLayout,
                               QLabel, QGridLayout, QLineEdit, QTextEdit,
                               QWidget)
 
 
class AddressBook(QWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
 
        name_label = QLabel("Name:")
        self._name_line = QLineEdit()
 
        address_label = QLabel("Address:")
        self._address_text = QTextEdit()
 
        main_layout = QGridLayout()
        main_layout.addWidget(name_label, 0, 0)
        main_layout.addWidget(self._name_line, 0, 1)
        main_layout.addWidget(address_label, 1, 0, Qt.AlignTop)
        main_layout.addWidget(self._address_text, 1, 1)
 
        self.setLayout(main_layout)
        self.setWindowTitle("Simple Address Book")
 
 
if __name__ == '__main__':
    app = QApplication(sys.argv)
 
    address_book = AddressBook()
    address_book.show()
 
    sys.exit(app.exec())

Hi,

Do you have the same issue with PySide2 ?

I am very grateful for your immediate attention.
I am a novice pyside user.
I have no experience with pyside2, so I can't give an accurate answer.
However, another pyside6 user in Korea recognized this as a bug and is hoping for improvement.
Example https://techclass.tistory.com/16 (Use Google Translate ^^)

Instead I provide other information from pyside6.
In QLineEdit, QTextEdit, QPlainTextEdit, and QTableWidget, there is a problem with the combination of Korean double consonants.

However, in the example using QGraphicsItem, I confirmed that the combination of Korean double consonants is 'Possible'.

And I tested QLineEdit to receive event as 'InputMethodEvent' and to print 'preeditString' and 'commitString'.
When 'ㄲ' is input, preeditString and commitString are print as follows.

preeditString= ㄲ
commitString=
preeditString=
commitString=

That is, it was confirmed that the event was received Twice when 'ㄲ' was input.
(Usually, if you input ‘ㄱ’, you will receive it only Once.)
So, I expect that the second preeditString is null(??) and cannot be combined because the two are sequentially input.

I hope my information helps a little bit in solving the problem.
Once again, thank you very much for your interest.
