What is Unicode?
http://unicode.org/
 Unicode provides a unique number for every character
 no matter what the platform
 no matter what the program
 no matter what the language
 The Unicode Standard [Unicode] defines the universal
character set.
 Its primary goal is to provide an unambiguous encoding of
the content of plain text, ultimately covering all languages in
the world, but also major text-based notational systems for
science, technology, music, and scholarship.
Unicode Support
 Apple, HP, IBM, Microsoft, Oracle, SAP,…
 Unicode is required by modern standards:
 XML, Java, ECMAScript (JavaScript), LDAP, CORBA 3.0,
WML, etc.
 Guidelines on the use of the Unicode Standard in conjunction
with XML
 Reference: http://www.w3.org/TR/unicode-xml/
