An issue with the complex input method output display.

On Windows, when using notepad.exe for text input(or any other programs that can receive text input), with WeChat input method and switched to Chinese input.
If you input 12：30, it will display as 12:30. (It recognizes this as a time and automatically changes the Chinese colon between 12 and 30 to an English colon).
However, if the same content is input in QTextEdit, the result displays as 12：:0.

This issue also occurs on MacOS. Using the WeChat input method and switching to Chinese input.
When inputting 12：30 in QTextEdit, the result still displays as 12：30 (it does not replace the Chinese colon with an English colon).
Whereas in other text input areas on MacOS (such as Terminal), it will replace it (changing it to 12:30).
