@shakespare, thanks for reporting. Please provide the requested info: "In the QGIS Help menu -> About, click in the table, Ctrl+A and then Ctrl+C. Finally paste here. Do not make a screenshot."
Does the Chinese characters appear if entered in other dialog window in QGIS? If yes, in what dialog windows?

In QGIS version 3.30.2 and 3.28.7, Chinese characters can't be entered , but can be pasted into SQL window, can be entered in other dialogs such as mesh calculator,raster calculator. I tested in QGIS version 3.26.3 , Chinese characters can be entered correctly in SQL window.

This is a bug in the QScintilla library -- it needs updating to 2.13.4 which includes the fix. Please file the ticket at https://trac.osgeo.org/osgeo4w/report/1?sort=created to get this updated in the Windows installer
