to make it conformant to the Unicode 6.1 specifications #14 and #29. The most important changes are: * The implementation has been reworked from scratch to fix all known bugs; * Separate-out the grapheme and the line breaking implementation to eliminate an overhead due to calculating unnecessary breaks; * Stop using deprecated SG class in favor of resolving pairs of surrogates; * A proper support for SMP code points; * Support for extended grapheme clusters (a drop-in replacement for the legacy grapheme clusters as of Unicode 5.1); * The hardcoded tailoring of UBA has been eliminated which breaks the 7 years-old lineBreaking test. Some later, we'll investigate if such a tailoring is still needed. Change-Id: I9f5867b3cec753b4fc120bc5a7e20f9a73d89370 Reviewed-by: Lars Knoll <lars.knoll@nokia.com>
