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
- Unicode 6.0:
- 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
- CLDR 1.9:
- Supports final version of CLDR 1.9 (#8156, #8201)

Version: 4.6.1
Release Date: 2011-03-11
- No API changes since ICU4C 4.6, see API Changes since ICU4C 4.4
- ReadMe
- 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

- #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
