Subject: ANNOUNCE: DJGPP port of GNU libunistring 0.9.8 uploaded.
Reply-To: djgpp AT delorie DOT com

This is a port of GNU libunistring 0.9.8 to MSDOS/DJGPP.


   This library provides functions for manipulating Unicode strings and
   for manipulating C strings according to the Unicode standard.

   It consists of the following parts:

     unistr.h     elementary string functions
     uniconv.h    conversion from/to legacy encodings
     unistdio.h   formatted output to strings
     uniname.h    character names
     unictype.h   character classification and properties
     uniwidth.h   string width when using nonproportional fonts
     uniwbrk.h    word breaks
     unilbrk.h    line breaking algorithm
     uninorm.h    normalization (composition and decomposition)
     unicase.h    case folding
     uniregex.h   regular expressions (not yet implemented)

   ATTENTION:  the support for DJGPP 2.03 has been dropped.  The DJGPP 2.05
   version of this port provides the libraries as DXE3 modules instead of
   static libraries.



   DJGPP specific changes.
   =======================

   There are only some minor adjustments required to get the gnulib code
   and test suite compiled with djgpp.  As usual, all files required to
   configure and compile the package are stored in the /djgpp directory.

   To be able to configure and compile the package you will need LFN support.
   This library depends on the iconv library.  This is true for comfiguring,
   compiling and using the library with your applications.  The iconv library
   is available as:
     <ftp://ftp.delorie.com/pub/djgpp/v2gnu/licv115b.zip>
   This library has been compiled using this iconv version.  Do not link with
   other versions, it may not work.

   You can build and use the libunistring either as static library or as a
   DXE3 loadble module.  Using DXE3 modules has the benefit that the size of
   the binaries that use libunistring will decrease considerably.  Also it
   guarantees that all programs use the same ported code.  Please note that
   the port of libunistring has been configured and compiled as DXE3 module
   but it contains both versions of the libraries.  The DXE3 modules and
   binaries compiled with them are stored in the gnu/libunistring-0.9.8/djgpp/dxe3
   directory of the binary archive.  The static version of the libraries
   and binaries compiled with them are stored in their usual place so they
   will be used as defaults.  If you want to use DXE3 modules replace the
   static version copying the contents of the /dxe3 directory to your
   installation tree.  The DXE3 versions of the libraries are always pairs
   of files.  One is the import library used during the linking of the
   application, the other is the DXE3 module loaded at runtime.  The names
   are:
     /lib/libunistring.a
     /lib/libunistring.dxe
   The files with the ".a" extension are the import libraries created by the
   dxe3gen tool. The ".a" extension for the import libraries has been choosed
   intentionaly so that linking rules in existing Makefiles do not need to be
   adjusted.  The sources have been configured for the CVS repository version
   of libc.a.  To compile DXE3 modules you must compile like this:
     make  MAKE_DXE3=y
   If MAKE_DXE3 is omitted then the normal static libraries will be build no
   matter which libc.a has been installed.  To run the test suite you must
   start make like this:
     make check  MAKE_DXE3=y
   If MAKE_DXE3 is omitted then LD_LIBRARY_PATH will not be set to point to
   the freshly build but still not installed DXE3 modules and the testsuite
   will fail because the test binaries cannot load the modules at run-time.
   To install the products start make like this:
     make install prefix=/some/dir  MAKE_DXE3=y
   If MAKE_DXE3 is omitted then every thing will be installed except for the
   DXE3 modules.

   Please read the documentation to become familiar with this product.



   This is a verbatim extract of the NEWS file:
-------------------------------------------------------------------------------

New in 0.9.8:
* The data tables and line breaking algorithm have been updated to Unicode
   version 9.0.0.
* In the include file unigbrk.h, the function uc_grapheme_breaks has
   been added to accommodate the new UAX#29 rules involving 3 or more
   consecutive characters.

New in 0.9.7:
* The license has changed from LGPLv3+ to "LGPLv3+ or GPLv2"

New in 0.9.6:
* The data tables and line breaking algorithm have been updated to Unicode
   version 8.0.0.

New in 0.9.5:
* The data tables and line breaking algorithm have been updated to Unicode
   version 7.0.0.
* In the include file uniname.h, the function unicode_name_character
   has been extended to look for name aliases.

New in 0.9.4:
* The data tables and line breaking algorithm have been updated to Unicode
   version 6.0.0.
* A new include file unigbrk.h is provided. It declares functions for
   grapheme cluster breaking, that is, determining the boundaries between
   graphemes. See the documentation chapter "Grapheme cluster breaks in strings"
   for details.
* In the include file unictype.h, constants are defined for the group of
   general categories LC ("Cased Letter").
* In the include file unictype.h, functions for associating canonical
   combining classes with names have been added:
     uc_combining_class_name
     uc_combining_class_long_name
     uc_combining_class_byname
* In the include file unictype.h, functions for the Arabic joining type and
   the Arabic joining group have been added:
     uc_joining_type_name
     uc_joining_type_long_name
     uc_joining_type_byname
     uc_joining_type
     uc_joining_group_name
     uc_joining_group_byname
     uc_joining_group
* In the include file unictype.h, functions for new predefined properties
   have been added:
     uc_is_property_cased
     uc_is_property_case_ignorable
     uc_is_property_changes_when_lowercased
     uc_is_property_changes_when_uppercased
     uc_is_property_changes_when_titlecased
     uc_is_property_changes_when_casefolded
     uc_is_property_changes_when_casemapped
   But it's recommended to use the case mapping functions from unicase.h
   instead.
* In the include file unictype.h, the functions for bidi class, formerly known
   as bidirectional category, have been renamed:
     uc_bidi_category_name   -> uc_bidi_class_name
     uc_bidi_category_byname -> uc_bidi_class_byname
     uc_bidi_category        -> uc_bidi_class
     uc_is_bidi_category     -> uc_is_bidi_class
   The old function names still exist, but are obsolete.
* In the include file unictype.h, functions for returning long names of
   property values have been added:
     uc_general_category_long_name
     uc_bidi_class_long_name
   The functions
     uc_general_category_byname
     uc_bidi_class_byname
   have been extended to recognize long names as well as short names.
* It is now easier to detect the subminor version: The value of the variable
   _libunistring_version and of the macro _LIBUNISTRING_VERSION now includes
   also the subminor version.
* The functions u8_mbtouc and u8_mbtouc_unsafe now handle ill-formed UTF-8
   input in a better way, that is more compliant with W3C recommendations.
* The functions u8_strcoll, u16_strcoll, u32_strcoll now produce results that
   are less dependent on the iconv implementation in use.
* The functions u8_strstr, u16_strstr, u32_strstr now perform in O(n) time
   worst-case, where n is the sum of the lengths of the argument strings.
