i think this you can very simple to reproduce ...
the first one is just plain broken in kodi
have a look if the problem might be the same Japanese and Chinese translations are not working · Issue #15154 · xbmc/xbmc · GitHub
If so you can workaround if you replace the font with the full version instead of the light version that doesn not include the fontset for "special" languages. Not sure how it works but you likely just need to replace the font at your kodi skin.
For chrome its more difficult, I have a look how to fix it.
