I'm puzzled. What is the "aha moment" here? Your point seems to be that Java
char != Unicode character. True. Exactly like UTF-8 octet != Unicode
character. The fact that half a surrogate pair is not a Unicode character
doesn't seem like breaking news.
Do you mean to say that use of UTF-16 character encoding in a programming
language is broken as designed? In the perfect language of your own design,
would you have the "char" type be 32 bits? Is that what this is all about?
