*** 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
with GDB while the target is running. "show target-async" displays the
current state of asynchronous execution of the target.
+set target-wide-charset
+show target-wide-charset
+ The target-wide-charset is the name of the character set that GDB
+ uses when printing characters whose type is wchar_t.

/* How GDB's character set support works
- GDB has two global settings:
+ GDB has three global settings:
- The `current host character set' is the character set GDB should
use in talking to the user, and which (hopefully) the user's
- terminal knows how to display properly.
+ terminal knows how to display properly. Most users should not
+ change this.
- 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. */

GDB has some support for translating between the two; GDB converts
characters and strings to the host character set before displaying
them, and converts characters and strings appearing in expressions
entered by the user to the target character set.
- At the moment, GDB only supports single-byte, stateless character
- sets. This includes the ISO-8859 family (ASCII extended with
- accented characters, and (I think) Cyrillic, for European
- languages), and the EBCDIC family (used on IBM's mainframes).
- Unfortunately, it excludes many Asian scripts, the fixed- and
- variable-width Unicode encodings, and other desireable things.
- Patches are welcome! (For example, it would be nice if the Java
- string support could simply get absorbed into some more general
- multi-byte encoding support.)
-
- Furthermore, GDB's code pretty much assumes that the host character
- set is some superset of ASCII; there are plenty if ('0' + n)
- expressions and the like.
-
- When the `iconv' library routine supports a character set meeting
- the requirements above, it's easy to plug an entry into GDB's table
- that uses iconv to handle the details. */

-Note that these are all single-byte character sets. More work inside
-@value{GDBN} is needed to support multi-byte or variable-width character

-
Here is an example of @value{GDBN}'s character set support in action.
Assume that the following source code has been placed in the file
@file{charset-test.c}:
distribution; if it is not, you can get the latest version from
@url{http://zlib.net}.
+@item iconv
+@value{GDBN}'s features related to character sets (@pxref{Character
+Sets}) require a functioning @code{iconv} implementation. If you are
+on a GNU system, then this is provided by the GNU C Library. Some
+other systems also provide a working @code{iconv}.
+
+On systems with @code{iconv}, you can install GNU Libiconv. If you
+have previously installed Libiconv, you can use the
+@option{--with-libiconv-prefix} option to configure.
+
+@value{GDBN}'s top-level @file{configure} and @file{Makefile} will
+arrange to build Libiconv if a directory named @file{libiconv} appears
+in the top-most source directory. If Libiconv is built this way, and
+if the operating system does not provide a suitable @code{iconv}
+implementation, then the just-built library will automatically be used
+by @value{GDBN}. One easy way to set this up is to download GNU
+Libiconv, unpack it, and then rename the directory holding the
+Libiconv source code to @samp{libiconv}.
