Hello Addison,
Thank you for your answering my question.
I am a Win-guru but our products support various platforms.
Anyway, my original curiosity comes from since UCS2 has 65K code points, it
could adopt almost Asian characters without having one byte NULL.
If I restate my question then, why UCS2 allows the one byte NULL on its
codeset design/implementation?
Is it simply just because to provide codepoint integrity or ?
Thanks in advance for your kind reply.
