Description
ICU is the premier library for software internationalization. ICU 4.6 is a major release of ICU, with new features, new APIs, and many bug fixes in data and code.
Major changes in ICU 4.6 since ICU 4.4 include the following:
Common Changes
Supports final version of Unicode 6.0
New UCA data for collation/sorting (#7264), with refinements from CLDR; this data is revamped for more effective use of collation weights, and noncharacters are now handled (#8007)
Support for 2,088 new characters, including the new emoji and Indian Rupee sign
Fully updated properties
Support for UTS #46 Unicode IDNA Compatibility Processing (#7144).
Alternate number symbols based on numbering system (#7599).
Compact collation tailoring syntax for reduced memory and disk footprint (#7015).
New collation [import] rule for reduced footprint and improved maintenance (#7023).
Fast string BiDi direction detection (#7772).
ICU4C Specific Changes
ICU 4.6 requires compiler RTTI to be turned on. Please see the ICU4C readme for more details (#7455).
pkg-config files for a standard way of linking against ICU (#6981).
Promotion to @draft (from @internal) for most regex functions that provide access via UText (#8102).
Regex support for a "find progress" callback (#7666).
Enhance regex APIs to support full 64-bit offsets and indices (#7813).
New regex API to set match and start position independently (#7949).
ICU4J Specific Changes
Common Updates in ICU 4.6.1
Common Locale Data Repository (CLDR) 1.9.1

No API changes since ICU4C 4.6, see API Changes since ICU4C 4.4
Known issues from ICU4C 4.6, still present in ICU4C 4.6.1:
A collation rule using the new star notation “<*” in which the list of characters following “<*” includes two successive APOSTROPHE characters ('') is malformed, but may not be detected and will produce erroneous results (#8204).
On AIX xlC v9, having certain patterns in the source directory path will cause intltest to not build (see #8211 for simple workaround as well as patch) - this is already merged into the maintenance branch for future 4.6.x releases.
#8571 (C only) U_HIDE_DRAFT_API does not operate on the correct set of APIs; might also affect U_HIDE_DEPRECATED_API, U_HIDE_INTERNAL_API and U_HIDE_SYSTEM_API
#8563 Wrong primary collation weights for some characters in some language tailorings (e.g., bn & my)
ICU4C 4.6 issues fixed in the 4.6.1 release:
#8199 ICU misparses numbers in scientific notation
#8200 Layout of telugu rutvam
#8211 test dep generation fails on xlC v9 with a numeric source path
#8225 Build errors on C++ code on HPUX PA-risc on nested namespaces/definitions
#8267 ucstrTextExtract does not pin start param or handle >2GB text
#8281 pkgdata failure with large CFLAGS
#8363 trap in usearch_search()
#8364 detect out of memory issue for Hashtable in low memory situations
#8378 Assertion failure in intltest spoof/testConfData
#8388 uloc_minimizeSubtag and uloc_addLikelySubtag have extraneous or missing character
