+# Adds folding information to Unicode data
+# Added as the third field after the 'Symbian:' marker in the following format:
+# Symbian:<grapheme-role>;<excluded-from-composition>;<folded-form>
+# where <folded-form> is null or a sequence of hex unicode values
+# separated by spaces representing the folded form of the character.
+# Usage:
+# perl -w UnicodeAddFolded.pl CaseFolding.txt < <output-of-UnicodeCompositionEx>
+#
