+# Unicode support
+
+GLib has support for various aspects of Unicode, and provides a number of APIs for dealing
+with Unicode characters and strings.
+
+There are analogues of the traditional `ctype.h` character classification and case conversion
+functions, UTF-8 analogues of some string utility functions, functions to perform normalization,
+case conversion and collation on UTF-8 strings and finally functions to convert between the UTF-8,
+UTF-16 and UCS-4 encodings of Unicode.
+
+The implementations of the Unicode functions in GLib are based on the Unicode Character Data tables,
+which are available from [www.unicode.org](http://www.unicode.org/).
