[Bruno Haible]

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
  unigbrk.h    grapheme cluster breaks
  uniwbrk.h    word breaks
  unilbrk.h    line breaking algorithm
  uninorm.h    normalization (composition and decomposition)
  unicase.h    case folding

It is now available in version 1.2.


==== New in 1.2 ====

* The data tables and algorithms have been updated to Unicode version 15.1.0.

* New functions u8_pcpy, u16_pcpy, u32_pcpy, similar to mempcpy.

* New functions uc_indic_conjunct_break_name, uc_indic_conjunct_break_byname,
  uc_indic_conjunct_break.

* New functions
    uc_is_property_prepended_concatenation_mark,
    uc_is_property_id_compat_math_start, uc_is_property_id_compat_math_continue,
    uc_is_property_ids_unary_operator
  and new constants
    UC_PROPERTY_PREPENDED_CONCATENATION_MARK,
    UC_PROPERTY_ID_COMPAT_MATH_START, UC_PROPERTY_ID_COMPAT_MATH_CONTINUE,
    UC_PROPERTY_IDS_UNARY_OPERATOR.

* New constant _libunistring_unicode_version.

* The UTF-8 decoder functions, especially u8_mbtouc, are now more Unicode
  Standard compliant.

* The *printf functions no longer support the %n directive, for security
  reasons.

* Fixed a bug in the *printf functions: In the %U, %lU, %llU directives, a
  negative width given as an argument did not trigger left-justification.

* The functions u16_strstr and u32_strstr now operate in worst-case linear
  time.

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify libunistring-1.2.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   rsa4096 2019-02-12 [SC]
        9001 B85A F9E1 B83D F1BD  A942 F5BE 8B26 7C6A 406D
  uid   Bruno Haible (Open Source Development) <bruno@clisp.org>

If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.

  gpg --recv-keys F5BE8B267C6A406D

As a last resort to find the key, you can try the official GNU
keyring:

  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
  gpg --keyring gnu-keyring.gpg --verify libunistring-1.2.tar.gz.sig
