Dear, Mr. Mark Davis,

I am Masahiko Maedera.

I have found your report about UTF-32,
and I think this is very nice.

To avoid user's confusion when UTF-8, UTF-16, UCS-4 are converted,
it is necessary to make same limitation of code range
for all of them.

UTF-32 is good scheme to restrict code range of UCS-4.
But there is a serious problem that UTF-8 is not yet limited.
Is there any scheme to restrict code range of UTF-8?
