Unicode Support in Various Programming Languages

Question

I\'d like to have a canonical place to pool information about Unicode support in various languages. Is it a part of the core language? Is it provided in libraries? Is it not

Answer 1

Java

Same as with .NET, Java uses UTF-16 internally: java.lang.String

A String represents a string in the UTF-16 format in which supplementary characters are represented by surrogate pairs (see the section Unicode Character Representations in the Character class for more information). Index values refer to char code units, so a supplementary character uses two positions in a String.
