Thai text is quite complex, the input sequence check is necessary,
in order to check the validity of the input text.

Also the input normalization is important, to make the consistency
of input, which is important in the pattern matching applications.

The Java 2 SE v.1.2.2 Thai Localization has implemented the
WTT Thai input sequence checking method and normalization,
and both work well.

But in Java 2 v.1.4, it seems that these two features are cutted off.
As the result, user can input the 'illegal' sequences like
'double-tone marks' and etc.


We request to bring these features back
 1) input sequence checking method
 2) input normalization
