Different language code for Magento 1.9 to Magento 2.3 migarion

Question

I have a multi store in my magento 1.9 and i successfully migrated to Magento 2.3.4

one of my stores have language code and store code set to zn_HK in my Magento 1.9 , but in Magento 2.3.4 there is no more zn_HK language code for the locale configuration, so i changed it to zh_Hant_HK

then i tried to create a csv for one of the module like this:

app/code/Vendor/Module/i18n/zh_Hant_HK.csv

"original","翻譯"

but when i switch the store, the language didn't change

and when i change to production mode i got this error:

zh_HK argument has invalid value, run info:language:list for list of available locales

should i change my store code to zh_Hant_HK or did i miss something else?

Answer 1

yes you should change that csv name and probably you might want to put that translation file into (assuming you may have a custom theme as well) app/design/frontend/Vendor/theme/i18n/zh_Hant_HK.csv
