Foreign characters e.g. chinese not displayed correctly

[Ozzie Isaacs]

Thank you for bringing my favorite windows editor to Linux.
In the most recent version 7.8.4 I've encountered an problem, while opening files with chinese characters these characters are only displayed as rectangcles.

whereas this characters (执一) are display in other editors correct:
.
I'm not sure, but I this this working in the previous version.

Can you tell me output of these command

locale | grep -e 'LANG=zh_CN' -e 'LANG=zh_SG'

locale | grep -e 'LANG=zh_HK' -e 'LANG=zh_MO' -e 'LANG=zh_TW'

Also tell which cjk font mint uses.

[Ozzie Isaacs]

The only locale on my system is de_De. So the output of both commands is empty.
(Normal terminal output. Should'n it depend somehow on installed fonts in the wine runtime? I don't know how to get this information).

Cjk I'm not sure about, package manager outputs this 2 installed fonts after searching for cjk beside some other not installed programms with cjk in the name.

[Taqi Raza]

Currently I use these checks for user current locale following then add changes to registry for cjk font if one of these comes up on first time setting up wineprefix.

locale | grep -e 'LANG=zh_CN' -e 'LANG=zh_SG'

locale | grep -e 'LANG=zh_HK' -e 'LANG=zh_MO' -e 'LANG=zh_TW'

I managed it to start a console from notepad++ (Excecute - external program and then cmd). There I could start the wine included writer. The "Noto" fonts are displayed there:

And if I change the font to a right one can enter chinese characters.

[Taqi Raza]

Yeah defualt font does not support cjk text.

[Ozzie Isaacs]

So what would be a solution, is it possible to install and use a fully unicode support font and use it as default font in notepad++?

[Ozzie Isaacs]

Just to make it clear: my problem is files with foreign characters are not displayed correct, not the menus in notepad++

[Taqi Raza]

You can try adding font to $HOME/snap/notepad-plus-plus/common/.wine/drive_c/windows/fonts then change font in npp settings.

Thanks. I tried it.
I found code2000 (http://www.alanwood.net/downloads/) or the gnu unicodefont (http://unifoundry.com/unifont/index.html) are suitable, they contain the characters I need (at least chinese and khmer).
Maybe it would be an idea to write some sentences in the wiki, so the next who has the problem can find a solution.
