on mac platform just as Edit Undo don't translate because fetchTranslationJson parameter is zh-hans.json but not zh_Hans.json.

also on windows 10 if you press alt when app start.

Thank you for taking a look at fixing this! Unfortunately we can't accept the change in this way because renaming i18n json files has a lot of side effects we want to avoid.

Instead, it sounds like the code which tries to use the translation files needs to be investigated and fixed to ensure it using the same language codes as the rest of the app.
