It would be more correct to say that Plane 14 was adopted by the Unicode 
Consortium in reaction to a proposal in the IETF to use illegal UTF-8 codes 
to encode language tags in plain text.

The Unicode consortium does not like the idea of language tags in plain 
texts, but liked even less the idea that this should be done using illegal 
UTF-8 sequences, so they provided an alternative.

Thus....
