As mentioned in draft TSCONV, there are mainly 3 categories of TC/SC
conversion. They are 1-1 , 1-n , n-1

In the case of 1-1 , do not to care about the meaning. the matching of TC/SC
can be achieved by a matching function or a finite matching table. That is to
say matching of TC/SC can be done as Uppercase/Lowercase English letter
(EX: A-a).

If we say matching of Uppercase/Lowercase English letter belong to
"matching of identifiers", what is different from 1-1 TC/SC ?

As regards to 1-n and n-1 , it need to know more information such as the
meaning of the phrase or sentence. Such kind of TC/SC would be deal in higher
layer service.
