Maximum Character Value and Collation

[alan]

I'm writing a tree structure to store strings and would like a maximum
character value to serve as a boundry.

Is there a universal maximum character value that will survive in
collation algrotihms? Is that value Character.MAX_VALUE?

Thank you.

No, that is only the largest value of type char (=0xFFFF). The maximum code
point value is Character.MAX_CODE_POINT (=0x10FFFF), which is the absolute
maximum in Unicode 4. For the next few decades, Integer.MAX_VALUE
(=0xFFFFFFFF) will be far beyond the maximum code point value, but it is not
valid in Unicode.
