Thanks for response, but there are still a few things unclear:
1.According to https://zhpatch.evemodx.com/#/theory, Chinese localization files do exist in the EVE client however it cannot be accessed directly. To access it this tool will have to monkey-patch the client at runtime without changing the client. Do you still consider that as “not modifying the client”?
2.Do you consider Chinese localization a legit localization though it has the files but is not explicitly available?
