 *** Changes since GDB 6.8
 
+* GDB now has support for multi-byte and wide character sets on the
+target.  Strings whose character type is wchar_t, char16_t, or
+char32_t are now correctly printed.  GDB supports wide- and unicode-
+literals in C, that is, L'x', L"string", u'x', u"string", U'x', and
+U"string" syntax.  And, GDB allows the "%ls" and "%lc" formats in
+`printf'.  This feature requires iconv to work properly; if your
+system does not have a working iconv, GDB can use GNU libiconv.  See
+the installation instructions for more information.
+
 * GDB now supports automatic retrieval of shared library files from
 remote targets.  To use this feature, specify a system root that begins
 with the `remote:' prefix, either via the `set sysroot' command or via

 /* How GDB's character set support works

+   GDB has three global settings:

    - The `current target character set' is the character set the
      program being debugged uses.
 
+   - The `current target wide character set' is the wide character set
+     the program being debugged uses, that is, the encoding used for
+     wchar_t.
+
    There are commands to set each of these, and mechanisms for
    choosing reasonable default values.  GDB has a global list of
    character sets that it can use as its host or target character

      characters the user enters in expressions (mostly host->target
      conversions),
 
-   and so on.
-
-   Now, many of these operations are specific to a particular
-   host/target character set pair.  If GDB supports N character sets,
-   there are N^2 possible pairs.  This means that, the larger GDB's
-   repertoire of character sets gets, the more expensive it gets to add
-   new character sets.
-
-   To make sure that GDB can do the right thing for every possible
-   pairing of host and target character set, while still allowing
-   GDB's repertoire to scale, we use a two-tiered approach:
-
-   - We maintain a global table of "translations" --- groups of
-     functions specific to a particular pair of character sets.
-
-   - However, a translation can be incomplete: some functions can be
-     omitted.  Where there is not a translation to specify exactly
-     what function to use, we provide reasonable defaults.  The
-     default behaviors try to use the "iconv" library functions, which
-     support a wide range of character sets.  However, even if iconv
-     is not available, there are fallbacks to support trivial
-     translations: when the host and target character sets are the
-     same.  */
+     and so on.
+     
+   To avoid excessive code duplication and maintenance efforts,
+   GDB simply requires a capable iconv function.  Users on platforms
+   without a suitable iconv can use the GNU iconv library.  */
