36 | /* How GDB's character set support works | |
37 | ||
6c7a06a3 | 38 | GDB has three global settings: |
234b45d4 KB |
39 | |
40 | - The `current host character set' is the character set GDB should | |
41 | use in talking to the user, and which (hopefully) the user's | |
6c7a06a3 TT |
42 | terminal knows how to display properly. Most users should not |
43 | change this. | |
234b45d4 KB |
44 | |
45 | - The `current target character set' is the character set the | |
46 | program being debugged uses. | |
47 | ||
6c7a06a3 TT |
48 | - The `current target wide character set' is the wide character set |
49 | the program being debugged uses, that is, the encoding used for | |
50 | wchar_t. | |
51 | ||
234b45d4 KB |
52 | There are commands to set each of these, and mechanisms for |
53 | choosing reasonable default values. GDB has a global list of | |
54 | character sets that it can use as its host or target character | |
55 | sets. | |
56 | ||
57 | The header file `charset.h' declares various functions that | |
58 | different pieces of GDB need to perform tasks like: | |
59 | ||
60 | - printing target strings and characters to the user's terminal | |
61 | (mostly target->host conversions), | |
62 | ||
63 | - building target-appropriate representations of strings and | |
64 | characters the user enters in expressions (mostly host->target | |
65 | conversions), | |
66 | ||
6c7a06a3 TT |
67 | and so on. |
68 | ||
69 | To avoid excessive code duplication and maintenance efforts, | |
70 | GDB simply requires a capable iconv function. Users on platforms | |
71 | without a suitable iconv can use the GNU iconv library. */ | |
