/* How GDB's character set support works
GDB has two 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.
- The `current target character set' is the character set the
program being debugged uses.
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
sets.
The header file `charset.h' declares various functions that
different pieces of GDB need to perform tasks like:
- printing target strings and characters to the user's terminal
(mostly target->host conversions),
- building target-appropriate representations of strings and
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. */
