+noccylabs/unicode
+=================
+
+This library adds support for writing unicode characters to the console. It will
+register a number of global functions for this purpose:
+
+ * `uchr($numeric)` - Returns the unicode character matching the numeric argument.
+ * `uprintf($fmt, $arg..)` - A wrapper for `printf` that enables `\u` to embed
+   unicode strings.
+ * `usprintf($fmt, $arg..)` - A wrapper like `uprintf` but for `sprintf`.
+
+
+## Examples
+
+To output a specific UTF-8 glyph:
+
+    echo uchr(0x1000)
+
+The same thing in a printf fashion:
+
+    uprintf("Unicode glyph x1000: \u1000");
+
