   Applications should always treat language tags as a single token; the
   division into main tag and subtags is an administrative mechanism,
   not a navigation aid.

In particular, I suppose there are examples involving Chinese (e.g., ZH,
ZH-TW, and ZH-CN) where the proposed behaviour is problematic.

True if one links those tags to different charset (GB, GBK, BIG5, CNS, CCCII, etc.) used for Chinese; 
but false from the linguistic point of view.

Now, could somebody confirm me if tags like FR-que, FR, EN-us, EN... should be linked to different charsets? if yes, which charset respectively? if no, then the above statement about Chinese is false.

Best regards.
