Created attachment 145391 [details] The CJK letters 日 中 are not using the correct font in Krita's Android version Some CJK letters are not using the correct font in Krita's Android version. I suppose we should assign Noto-Sans-CJK fonts as the default fonts for CJK translation.
Created attachment 145392 [details] The CJK letter 上 is not using the correct font In this screenshot of Create New Document dialogue, the CJK letter 上 from 添加上述尺寸到预设 is not using the correct font.
It is also possible that Krita is using a wrong priority order of the subset of the Noto-Sans-CJK fonfamily. The font family has 5 language variants (HK/JP/KR/SC/TC), each with 7 weight styles. It looks to me that Krita is using a Thin/Light variant for those affected letters.
Or, it is also possible that Krita sees the OS's default font (which is not Noto-Sans-CJK on my phone) as higher priority. But it's still weird that only a few letters are affected.
I can't reproduce this on my device (running LineageOS 15.1). CJK text renders fine for me here with 5.0.2.
I'm using MIUI 12.5 International on a Mi 10T Pro (Hong Kong version). Language is set to Simplified Chinese. I'm pretty sure MIUI is using a unique default font other than Noto-Sans-CJK, maybe 小米兰亭 Pro. There is no way to customize MIUI's system font to confirm though. I'm also sure that all major Chinese manufactures has their unique default font as well. It's also possible that MIUI International ROM has some weird font issues, the font style looks less coherent than the mainland version. I will test this later on a mainland Chinese MIUI.
I was able to get the fonts displayed correctly by using Configure Krita > General > Window > Custom fonts.
