Description
There seems to be a font rendering issue for CJK characters, using the default settings, they are rendered using a different set of fonts, instead of a single one. Not sure how the font selection operates under Windows, but the issue isn't reproducible under Microsoft's notepad. Is there supposed to be a way to select or force a specific font for rendering?
Notepad++ v7.8.5 (64-bit)
OS Name : Windows 10 Enterprise LTSC 2019 (64-bit)
OS Version : 1809
OS Build : 17763.1192
Attached is my system font list (relevant ones are Google Noto CJK, Adobe Source Han and GNU Unifont along with the defaults Microsoft CJK) and a screenshot at several font sizes.

Research direction
Start by reproducing the CJK rendering behavior on Windows 10 using the reported Notepad++ version, installed font list, and screenshot. Then trace the editor's font selection and rendering entry points; done means the cause is identified and the expected behavior or a way to force one font is established with a verified result.
