Re: Widgets i18n feedback

Thank you very much for these comments, Addison. My personal +1, given 
now to help speeding up the process a bit.

Regards, Felix.

Internationalization remains a problem because JavaScript has no locale facet. Internationalized formatting and processing is only possible as long as one is happy with the default system locale and formats on the host platform. Note: this is usually less of a problem for widgets than for AJAX style interactions in a Web page, since most widgets are perceived as applications running locally, whereas most Web properties manage the user language/locale themselves and need a locale in JS to "do the right thing".

The packaging format MUST either provide for a declaration of the character encoding used or specify what it is. The UTF-8 character encoding SHOULD be either the default (if multiple encodings are allowed) or sole encoding used.

If the UTF-8 encoding is not used, the specific encoding MUST either be specified by the packaging format or be specifiable in the package itself. Since packaged widgets are widely distributed, variation in character encoding between different platforms or configurations may render a widget with non-ASCII resources inoperable or otherwise degrade the user experience unless a comment character encoding is used.

If the zip relative path is encoded using [UTF-8], then the general purpose bit 11 of the local file header must  be set to 1, otherwise it must be set to 0.

> I'm pretty sure you do not mean "characters" here. You probably mean "bytes", since that is the limitation on some operating environments. In a multibyte encoding, such as UTF-8, this means that there may be fewer than 255 characters in a 255 byte sequence (as few as 63 in the worst case). Please use the word "bytes" here if that is what is meant and include a note along the lines of: "Note that a character can require more than one byte to encode, making the length of the path in characters less than 255."

Even more confusingly, the word "token" doesn't even appear in 3986 and appears only once (in another context) in 3987. I think you should specify the specific format, preferably IRI.

Ideally, you should permit multiple descriptions (at least) in multiple languages. These elements are often displayed in widget management environments (before the widget is invoked or running).
