When i add "default_locale": "en", to my manifest file, then package it and try to upload it, i get the error message saying, An error occurred: Message JSON file must be in UTF-8 encoding. ... But this is how they tell you to set it up in their i18n page... What is the problem?
回答1:
I'm not sure he's missing the Byte Order Mark -- which is neither required nor recommended in UTF-8 (as endianness isn't relevant) -- I think it's just the file encoding. I believe Notepad adds the BOM by default when you save as UTF-8, but I always save files without it as some programs that receive UTF-8 data don't expect the BOM.
But yes, bottom line, go to the file and Save As in UTF-8. If you are using Notepad, I'd recommend using a different editor -- for JS something lightweight like Notepad++ works well -- so that you can change the default encoding, among many other benefits.

It seems that you simply missing Byte Order Mask in front of your manifest file. If you are on Windows simply open it in Notepad, click File -> Save As and choose UTF-8 from Encoding combo box.
Obviously you can use other tools to "convert" to UTF-8...

just solved the issue... After googling awhile... turns out MS notepad is inadequate even with utf-8 encoding... Download "Notepad2"... and set the encoding to utf-8... somehow it works now!
