Details

I think we need a way to iterate, both forwards and backwards, over the default grapheme clusters in a string of text. (Such a mechanism could live on top of a mechanism for iterating over the characters in a piece of (UTF-8 or UTF-16) text.) For the definition of default grapheme clusters, see: http://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries http://www.unicode.org/reports/tr29/#Default_Grapheme_Cluster_Table and for why this is needed, see the dependent bugs, bug 329069 and bug 332739. We may want to do some tricks involving glue libraries for this: we could have the data live in the i18n library, but have a tiny glue library (probably part of unicharutil?) have code that loads the pointer to the data into each library that needs it in the module ctor so we don't need virtual function calls or cross-library calls to load the pointer.
